Yeah I have thought about it lots, not least because I actually started doing this on the FFFox Mod version of the game
And I do like quite a bit of the added content, especially at the time before Inusuku added his own versions of a lot of events (the akapp cut-ins for undressing are super nice for example but Inusuku took the "show me your underwear" option to another level in the DLC). But on the same token, I find it hard to justify adding things to the game that I personally don't enjoy, so it becomes a bit of a mixed bag and makes me uncomfortable.
Even without me though someone could port the whole TL revision to his version. It's not specifically hard, just tedious to copy out every line into the correct text file. Would optimally want a bit of re-writing for style on the original/modified content but for the most part it'd just be a whole lot of ctrl-c ctrl-v.
