Certainly some interesting ideas. I will say that in terms of broad stuff like this, there's basically an infinite number of possibilities, so I'll probably mostly end up going with my own stuff. A lot of it isn't even planned and just presents itself as I'm working on the game. The entire hostclub in GT exists because of a store sign that was in a tile set I was using. That said, will see if an opportunity presents itself though, doing some interesting things with items especially might have some potential.
