Really curious as to what made you go and figure this out.
Fives seems like a more reliable speed down character.
This seems really RNG dependent to set up correctly. Escape or kill 3 of them? Two are stealthed like the Jawas, and one has foresight. So maybe if you had strong Jawas but undergeared toons for the other three. But you still need R2 fast enough to do smoke screen before the guns (speed 235, is it?) kill him, so he can't be TOO low gear.
Also, relying then just on the two Jawas to topple without getting killed or having their stealth wear off? At 167 speed? Are you sure you didn't mean NAAT?
I'd really like to see a video of this ACTUALLY working, because it seems hard to set up.
Also I would say mainly just p2, as in p4 you have to stun or kill the B2s before you try and put speed down on the tank, or they will remove your foresight.
