If so, probably not going to happen without a LOT of work. The Maverick is a unibody, so it doesn't have a frame like a conventional pickup truck. The side of the beds are structurally necessary. You would have to add a lot of metal, in the form of beams or something, to make this work.
I don't know if the attached image is intended for someone building a flatbed truck or if it just identifies where the Maverick's frame (subframe?) may be found.
