Actually, a Bakugan Battlefield map would be pretty cool. All it would require is a simple slate edit, of course, call it something else: "Slate Interdimensional", maybe. If you want to know what it looks like, 0:53 of
this video shows the sky pretty well, except that there are swirls of Yellow, Brown, Red, Purple, Blue and Green, the ground is pure white. Give this suggestion a chance, even though the game and show may suck, a Battlefield map would look pretty decent.
Edit: 4:29 shows the ground pretty well.
