I would think that since the VX is basically a body on a frame that the doors wouldn't offer that much structural stability. Heck, you may even be able to chop the top off without many issues. May need to beef the frame up a little bit, but that might be it.

Did anyone get a picture of the underside of the VX02?

A lot of the Rodeo and Trooper guys who are highly modified run without doors in Moab.
