I don't have github experience I'll get around to it =D
I tried 
https://github.com/koxsos/endlessWaifus

ok, status update:

I freaking figured it out.

Will upload the updated version with assets properly replaced.

the faction leader screen is a fickle thing, as you need more or less a center character with some okish background for 360*180

So a happy bump, proof of concept is done, it's time to jump up the bandwagon you lurkers and at least get some assets rolling in! ^_^
I'll get started on changing Cravers to overlord cast next.

Here's what can be optinally used in addition to heroes:
