Anyway, Haze and Roar are valid options, but are generally limited to walls. You could always run them on a sweeper, yes, but you'd lose out on valuable coverage needed to sweep.
Switching out your wall for a sweeper would be the best option, but the opponent could always just Double Team some more, and then the cycle would repeat.
Clear Smog is a lot like Haze, just with a more limited pool of viable Pokemon that can learn them. M-Venu and Amoonguss are the first that come to mind, along with several other poison types.
The problem again of them being mainly walls comes up, however. You could reasonable throw Clear Smog on a M-Venu, no doubt, but like the other sweepers it'd have to either drop coverage or a stronger STAB for it, and really, you need all the damage you can get if you're going offensive M-Venu.
Aerial/Shock/etc are just worthless almost entirely. Even if they opponents aren't walls, the damage is only base 90 accounting for STABs, hardly strong enough to KO out anything, even with hazards on your side.
Besides, if they're sweepers themselves, they could easily KO you with one of their moves. If they're walls, they can just stall and recover off your piddly damage.
Anyway, you should really be arguing this on Smogon if you're so adamant on evasion being allowed. I just wanted to throw in my two cents earlier there.
