In this case (changing an item filename) I think not - it is merely a technical change. Meaning it takes place in the .d files but not the .tra files. Though I don't know if Hoppy made other dialogue changes that might affect .tra files.Dialogue...change..there are new translations to do...
You're correct with the item code change was all that was needed. It is in cyberspace on the SHS temp server but my message to Liam has yet to be read.
