Can anyone make Player models or NPCs of the main characters for Garry's Mod?

[Videogameking]

I am a HUGE fan of this game and I love the sisters in the game! And I was wondering, is it possible to port them into Garry's Mod? Is it possible to convert the LUA files and all that fancy tech stuff to make them Player models and NPCs? What I'm trying to ask is: can anyone do that for me? I know i'm a nobody and not a lot of people played this game, but I was wondering if there was any fan of this game like me who also wants them in Garry's Mod. I would do it myself, but I don't even know how to get addons from Garrysmod.org! So if anyone out there takes recommendations, could you please do this for me?
