I know it's incredibly unlikely. I know it would require a whole host of extra work making flavoursome cards / maps / quests / character models etc. But I don't care! It would be PERFECT I TELLS YOU! Honestly, I just want to be able to use Thog to play Bash. Then all will be complete in the world.
If they just released some special edition (for pizza presumably) character images with OotS characters, I don't think that would require a ton of extra work. Extra skins seems like the easiest implementation of a feature like this.
Well, theres' the matter of licensing unless they're being allowed to be used for free - the implementation itself is probably not a problem technically.
I've been saying this since day one (well, day one when I found out about Card Hunter). Especially since Rich has been creating a series of OOTS themed cardbolard cutout figures for gaming which look exactly like CH actors - they could just use those pretty much verbatim. I'm sure a deal could be made with Rich since he wouldn't have to do anything and could get a cut of whatever the pizza cost of buying the figures was.
