Schluter kerdi membrane install on shower stall floor.

[Dittybag]

I have part completed shower stall with a partial Schluter kerdi membrane install on the floor. Can I pour Levelquick over the Kerdi? Then new Kerdi on top? It seems the slop to the drain is too steep and I want to reduce it to 1/8" per foot. The shower is 78" by 48" if that matters
