I think it would be cool if you introduce a whole new genre into rap music, do something that no-one else is currently doing.
I'm not sure what, but if I knew, I would do it myself and make some $$$
But all you have to do is look at artists like Eminem or even Kanye West to see that bringing something fresh to the rap scene is always interesting.
Maybe it could be something new in the way you make beats.
Maybe it's something about your stage shows that could switch things up.
Maybe it's your entire theme like Insane Clown Posse for example...
Those are my ideas anyway, good luck dude!!
