Well, I think it *is* possible. I could see it being done with say one flap, being stored in the wing root and then pulled out to cover the hinge.. but, that wing root also has to hold the rear wheel well. I don't know if you would get the smooth surface you want either.
I wouldn't mind the gimmick, in fact, i would prefer it to some other gimmicks discussed here... I just don't think you should get your hopes up.
