There's lots of mod ideas out there. Here are some that I am fond of that I believe are feasible.
1. Prologue NPCs: Canderous, Arkanis, Osprey, Mordaine, Deder - In vanilla BG, without tricks these NPCs stay with you for one battle in the prologue and then disappear. With tricks, you can get them to stay, but they're largely silent. It would be really awesome for these NPCs to be easily recruitable in the Prologue (or Chapter 6) and be fitted with personality and banters. One would be able to play throughout the entire Baldur's Gate Trilogy with the same party.
2. Return and stay in Candlekeep mod - CHARNAME should be able to return to Candlekeep given the recent death of his father. CHARNAME should be given the option to stay at home where it's safer instead of adventuring out into a dangerous world. The events of BG1 would unfold differently.
3. Gorion NPC - In D&D, death is rarely permanent. Gorion is no different. Gorion will leave a corpse on the ground that can be taken to a temple in the game to have Resurrection cast upon it (or resurrection can be cast by the PC or NPC or by a magic item). Gorion will then become a joinable NPC who will travel with you throughout the entire Baldur's Gate Trilogy. A few changes in ToB when necessary: Wraith Gorion will be changed to Wraith Aliana. Dead Gorion's words will be said instead by the living Gorion in party or suddenly teleported there. Gorion may have to occasionally remind people that he's alive.
4. Tamoko NPC - If the player doesn't kill Tamoko, she'll be found later in BG2 or TOB. Interactions with Sarevok, Yoshimo perhaps, and a different Sarevok Epilogue to boot.
5. True BG1 to BG2 NPC Continuity mod - Make Baldur's Gate Trilogy and/or Enhanced Edition Trilogy do what players have been wanting for years: Enable a party in BG1 to remain together for the entirety of the game until the end of Throne of Bhaal. BG2 no longer assumes that your BG1 party was CHARNAME, IMOEN, KHALID, JAHEIRA, MINSC, and DYNAHEIR. Whoever was in your party at the end of BG1, will be in Irenicus's Dungeon. NPCs will appear in the multiplayer cages and will appear in place of where Minsc and Jaheira were, ready for you to rescue them by finding all 5 cage keys. If Minsc and Jaheira weren't in your BG1 ending party, they'll appear where in a vanilla BG2 game they'd be kicked out. Dialog will be modified to account for the different events.
Dead NPCs will not re-appear. If Quayle died in BG1, he won't appear. If Xzar died, he won't re-appear. However, Biff the Understudy-like characters will replace dead BG1 NPCs or BG1 NPCs that vanilla BG2 assume traveled with you. Ex. If you transitioned from BG1 to BG2 with Edwin or Edwin died in BG1. You can leave Irenicus's dungeon and go to the Thieves Guild to find another Wizard who will give that Thieves Guild Quest. If Safana and/or Coran died or traveled with you from BG1 to BG2, you would find a different lover or pair of lovers. If Imoen died in BG1, a different green-haired female Bhaalspawn Thief / Mage will free you from your cage in Irenicus's Dungeon. Your quest in BG2 will change to rescue this woman that you barely know (who also happens to be your sister) instead of Imoen. Biff the Understudy-like characters will be joinable if who they replaced was normally joinable.
For Enhanced Edition Trilogy. The mod would ensure that Adventure Y would start out with all the BG1 NPCs present at the end of BG1 and would ensure that at BG2, all the NPCs present at the end of Adventure Y would be present in BG2 in Irenicus's Dungeon.
6. The One Branwen mod - Combine all the content from the Branwen mods together in one Branwen NPC
7. The One Kivan mod - Combine the content from the Kivan mods together in one Kivan NPC
8. The One x mod - Combine all the other relevant mods together to ensure one Yeslick, one Quayle, etc.
9. TDD Revised Mod - Add banters and interjections for all TDD NPCs and breathe life into them. Remove BG1 NPCs as there are other mods that address these NPCs better. But, add modding options to add their quests if another releveant BG1 NPC in SoA type mod is present. . Make TDD quests an optional component. Add TDD sin TDD merchants to the game. These last two items will remove the need for TDD sin TDD mod.
10. Ehlastra NPC - This is the slave woman held in Yaga Shura's Stronghold. In vanilla TOB, you can ask for her to join, but she will refuse. I think she'd make a great NPC companion. Her dialogue file is named YAGCON.DLG
11. New ToB Ending: Resurrect Bhaal - After Amelyssan tells Bhaal to "remain dust my foolish god" and before you're teleported to the final battle, a cutscene will occur in CHARNAME'S MIND/SOUL with Bhaal speaking to him/her and asking CHARNAME to defeat Amelyssan and restore Bhaal to life and divinity. At the end of ToB, when CHARNAME decides to become a god or give it up, another option will appear allowing CHARNAME to give up all the essence of Bhaal (including his/her own) and ressurect Bhaal. The Solar won't like it and may fight CHARNAME. Good aligned NPCs won't like it and will fight CHARNAME. Evil NPCs will like it! At the end of this battle, CHARNAME will complete the essence transfer and Bhaal will be ressurected. A new Ending Epilogue for CHARNAME and some possible different epilogue endings for NPCs: romantic and otherwise.
