Unfortunately so far I've been stumped with trouble with the file extension. Since I run FTL through Wine on Ubuntu (admittedly I'm fairly new to the OS), it doesn't seem like a simple renaming of .zip to .ftl has been working; no matter how much fiddling I do with the folder name/extensions I still get a "unsupported folder" problem from the mod manager, and I'm [pretty certain ubuntu has the display file extension option on by default.
Unless someone has a solution that I'm too stoopid to figure out, it would be great to see an already-formatted .ftl version of the mod on mediafire or something that isn't picky like moddb
