Is it possible to recreate the entirety of the final boss of Pizza Tower in GKC?

It is a Wario Land 4 inspired game about an Italian who, in debt, is threatened by a giant sentient pizza to explode his pizzeria with a laser if said Italian doesn’t climb the Pizza Tower to stop it (the laser is a lie). The boss is a huge, 5 minute and 7 phase fight, which is why I was asking if it was possible. Does this clear it up a bit?

EDIT: there is also another topic I’ve helped in recreating most of the game in GKC, you can go to it here:
