idea What kind of romhack should I make for the ORAS Demo?

[Alerdy]

Lately I have been messing with the ORAS demo, with RSWE, RSTE, and Ohana. I have managed to do some pretty interesting things, enough to make a public hack. But I don't know what exactly should I change. So the question is, what kind of romhack should I make for the ORAS Demo?

I'm thinking of making some Pokemon ORAS: Funky Demo Version where everyone looks like a popstar, lol. See, I have bad ideas, so that's why I am asking the community.
