No, this project is limited in scope to the OT films. However, I've designed this project as a sort of complete subtitling toolkit/template so that others can build on what I've done, as needed. So, while I don't personally plan on any expansion more radical than adding languages, that's not to say someone else couldn't use some of my tools and workflow to create something different.

EDIT: Oh yeah, and you're very welcome. Making these films accessible to deaf viewers was in fact the whole reason this project got started. It just got a little out of control...
