SUper mario galaxy 3 ideas

i loved the first 2 mario galaxies. I would love a third. let's share ideas for it. For exsamlpe i want treasure hunt levels with red stars

I say screw calling the next Mario SMG3, what they should do is Super Mario Universe instead. Having as many characters from the Mario franchise as possible, I'd like to see Princess Daissy make a return.
I also want a remix of this:
Dire Dire Docks

Back in the Mushroom Kingdom.
