I'm not sure I like the Sleight of Hand check. However tricky the golem is shouldn't affect how sickly the victim looks, for example.
That's probably a reasonable list for the immunities, though I could see dropping immunity to mind-affecting, especially if it keeps the Wis and Cha of the base creature.
Seems strange to me that it could gain or lose HD, though I could see swapping construct bonus hp for usual Con-based "bonus" hp. HD are a basic property of the creature; alternate form and change shape don't change HD, and even the more powerful polymorph spells only change HD in a limited way.
