My character started out as a dwarf cleric, but he died a couple of times. He was brought back to life each time via reincarnation which changed his race.

He was an Orc, then became a human, and is now a half elf. He still has the mind of a dwarf, and has finally found a way to turn back into his original form (that doesn't involve another dwarf dying).

He wants to use a permanent polymorph spell on himself so that he can turn back into a dwarf (since I am soon to prestige or split class, and the way I want to go requires I be a dwarf). Since my DM says that my character still has the mind of a dwarf even in a half elf body, would he gain back the racial feats and traits that came with being a dwarf?

Any help would be greatly appreciated.
