Are you sure you tried Sniper Attack? I was on Sniper Attack on Corvette earlier and the Elites appear on the 5th wave. As far as I know the waves are always the same (I've done Sniper Attack on Corvette quite a few times). Managed to rack up 8 Elite kills and then I finished the Round not long after. It's pretty easy really when you have Sniper Rifle and infinite Ammo.
