I would probably play it for fun, for the absurdity of seeing characters in such a setting, but I can't imagine it would have much sex appeal to me. The graphics look decent, but I would really like to see some adjustment to the stock Renpy UI and font. Like the screenshot with the choice, it doesn't feel like it fits the universe you're building. No idea how hard it is to adjust though.
But hey, go for it, have fun with it. After all, if you don't have fun with it, you're going to struggle to keep up the current level of motivation.
