Traditional Galley Hatch on Square Teardrop

Howdy,
I'm looking at building a squared-off teardrop per the design below, which I found in the archived design library here on the forum. This, and almost all the other squared off campers I've seen, have a combination of galley hatch for the top and traditional doors at the bottom (with the exception of the Desert Dawg).
My question is, what is preventing a traditional, full-height galley door on a squared-off teardrop?
Thanks!
Kristian
