Banana trees and vines

Hopefully this will be easy to answer: in a permaculture guild garden setting, are banana trees able to support vines? Could they support the delicate winter sweet pea type vines? What about more vigorous pole beans? Would it be crazy to send cucumbers and butternut squash vines up the banana pseudostem?
Would the sweet pea vines help insulate the bananas during winter? I'm in central FL 9b and it is rare I ever see frost in my yard, but I'd like to make sure the bananas stay warm.
I have two banana pups. One is a Musa Gran Nain and the other is a Goldfinger.
