drywall ceiling repair with heat cabling

We recently had a water leak in the master bath that dripped onto the first floor ceiling. Opened up the ceiling drywall (carefully, you’ll see why below), determined it was from the shower pan, not the toilet, and repaired the problem.
The ceiling is roughly 7/8″ thick; rockwall attached to the joist(?) followed by heat cabling, then another sheet of board and then a finish coat on it. The hole I made, to eliminate the water damage is about 6″ diameter. The wiring is approximately 2″ o.c.
Question is how to reconstruct the ceiling, keeping the exposed heating cable in place.
Thanks – Don

Normally you can cut a piece of drywall as a patch, sized about 2-4 inches larger than the hole to be filled. Outline the hole on the back of the drywall, cut it out, but leave the front face intact to act sort of like a flange. Mud up the paper flange/edge of hole, apply patch to hole, and coat as required.
Often I insert some sort of wood support glued/screwed to the drywall prior to appling the patch, but your cable wouldn't lie flat if you did something similar. The paper flange trick should work, provided the patch isn't too big.
Anything you can think of that might prevent this from working? (Only you know for sure what the situation is...)
I agree with Nick.
6x6 inches can be held by a drwall patch with backing screwed such as plywood . Two 1 1/4 inch strips of plywood and SR screws make a good job.
But as Nick says , were not there to see it .
