Knowing Zeppo, he'd probably had some idea of surprising the first trooper that would open the door and wrapping the jacket around their head for some reason. And in this case, improvising probably means stealing another ship of some kind. Stealing a ship seems unlikely to happen; or at least, I hope it wouldn't mean the Falcon gets left behind with the MacGuffin Modulator.

Problem solving by creating new problems that aren't his? Oh no; it's a sign! Zeppo's turning into management! This is going to make Finn's job of betraying the Resistance much easier if Zeppo keeps this up. Though actually..... maybe that's not the case any more? With that scene, it's hard to tell at the moment here if Finn is actually still a traitor or is in that spot where he thinks nobody is on his side, so everyone else is fair game for backstabbing.
