Contractor messed up shower pan. Fixable?

My contractor who I'm firing tomorrow messed up my shower pan. He used sand mix concrete to form the base but the back side (against the wall) is a good 1/4" to 1/2" lower than the front. It does slope towards the drain in the front but of course the back is too low. He did use a rubber liner under the concrete that wraps up and behind concrete backer board.

I'm firing him as I have no confidence in him to get this right as he also messed up the floor tile I now have to take up. In any case, the question is if I can (after removal of the shower pan tile) fix the pan without removing it? Is there a product I could mix up that would adhere decently to the existing pan concrete I could smooth out and make the back of the pan match the front with proper slope? I would also like to use waterproofing "paint" such as Aquadefense before retiling.

I'd really like to avoid taking out the current concrete as I fear damage to the underlying liner if I do that.
