You can't /give yourself extra body parts, but you seem to be able to remove them. The /remove command works with feet and fists, or at least the server will tell you it does. You're still able to attack with both.
I understand why, but the command also removes any melee weapon you're currently holding.

Discovered in Pre-Alpha 1.9.2b

That's a bit silly. Disabled /remove name fists/feet after Pre-Alpha 1.9.2b.
