I was thinking about it, and maybe a lot of us had the wrong idea about MIB needing Locke's body.
Maybe he can just imitate the dead, and only needed Locke to kill himself. The body was brought back as part of simulating the conditions of 815.
MIB needed Locke's body brought back so people, namely Ben and Richard, would believe that Locke had risen from the dead and they would then take him to Jacob.
That could be why he said he needed the body brought back.
That would put rest to the idea that he needs the physical body of a dead person on the island to replicate them. It just so happens that the body of everyone he has posed as is on the island, except Isabella.
That's the best I got right now. An episode highlighting MIB's history/powers is really key
