I've looked into multiple images in the past, but ran into issues that I didn't have time to work out. One thing I'd LIKE to add is the ability for other mods to override the sprite prototype used, and optionally override with a custom animation prototype. After a quick investigation today it seems the former isn't too hard but the latter for animations breaks a lot of runtime code and I don't currently have a good solution for fixing it. (See vp_generate_sprite_for_player)
If you're open to working on the mod, the source code is available on Git to have a look at. I'm trying to avoid spending time on large changes to the code for a bit until after 2.1 comes out, as there's a non-zero chance this mod becomes obsolete then. (Which I'm all for, a base game implementation of this mod would be awesome)
