Ok. I've got a bit of work to do to clean it up, but I think I have managed to recreate the EnglishT.lod file for MM8 from an exported directory of the same files.Without actually playing MM8, it's hard to say if something was overlooked.
If you want to be an alphatester, send me email, and I'll build you a copy and explain the set of steps needed (for now, choose a EnglishT.lod, extract all files into a directory, make changes to those files, then "import all" to rebuild EnglishT.lod.new in your data directory, which you could then rename and give a try.
I need to make this a little more user-friendly before I release an official package. It also only works for EnglishT.lod this version (actually, it might work with EnglishD.lod as well, but I didn't try it yet.)
