Talking about airships, I find them pretty cool too. This is what I'd do:
Fire Cannons and lots of Bullet Bill Blasters;
Bob-ombs for exploding stuff;
Custom Obstacle Boxes (Replacing Mother Brain's Glass);
Arranged Thunderbolts for even more exploding stuff.
Metal Boxes (NSMBW);
Red Coin Rings? Maybe.
HEY, THIS GAME SERIES IS FUN.
You could even say that...
