P2 haat possibility?

I decided to try a run today Rex lead, Vader, maul, zkylo and r2, with little effort I put up almost 400k with 3 topples. The next raid I'm thinking about trying zmaul lead, vader, savage, r2 and zkylo, my thoughts being keep everyone except kylo stealthed. In my run today I hit smoke screen right away and by the time topple ended it was off of cool down ready to throw back on kylo.

I know this isn't an optimal team, more of a throw together squad for more damage as I really only participate in p1 and p3 atm.

Anyone tried this combo with the zmaul squad or similar? I feel there is potential for a lot more damage using the r2/zkylo combo.
