though even taking that in to account, it really doesnt make sense that someone that has been so mauled/disfigured (falling into lava does that) would grow...build muscle mass maybe, i mean their technology is much better than ours (bacta tank) but as far as growing taller thing I think id have to agree that maybe he would gain 3-6 inches from the suit (think about it, boots add height, thickness of the helmet, space between top of his head and the helmet), but thats it. Dont feel like looking back for what the actual height difference that needs to be made up is, so not sure if that would do it, but its food for thought.
