Usually it's just any wall splat move (e.g 236P) > 33P > 3PPP.Ah gotcha, will test tonight but it sounds like the one you provided does more damage too. What about for splatting them into a wall?
There are also some good moves that cause a wall splat but leave her in a specific stance, in that case just do the "refloat" move of that stance into 3PPP.
6H+K > DS K > 3PPP
4K2 > DCK K > 3PPP
214P+K > BKO 4PK > 3PPP
HC P+K > HnK K > 3PPP
The only exception is 8K, on heavyweight she can only get a Bokuho PPP so it's not worth to use it here.
