Would it be possible?

Actually, if you're prepared to have your brain slowly melt out of your head you could do it with planes and not have to use a single new model. Of course, like I said, doing that legitimately would make you go crazy and you wouldn't be able to have it rock back and forth, but you'd be surprised how much you can do with planes. Just as an example, for the last few days I've been working on a barn, and this entire thing is made completely out of planes and welders.

Spoiler below!

I dunno, just a possibility.

Turn it upside down and you got a boat : P
