Sure, that's definitely ok too, each to their own! I think it will take quite a bit of time for the full game to be released though, so hopefully that sets the expectation you have in mind :)
Regarding adding a Mishima route, I will only consider it if a writer-slash-coder comes up to volunteer to write for him. As of now I have my hands full with writing for two routes and scripting for 80% of the routes, on top of other enhancements to the game, sooo yeah haha
