Mortar pan into drywall

So most of my showers I’ve done I’ve done my mortar bed and ran the liner up the wall 4 inches, then done backer board. Alternatively a customer I’m beginninng now has dry walled the whole shower down to the plywood. What is the best way to do this mortar bed and tie it in with the drywall? I’m planning on using Kerdi waterproofing after.
Side note. I thought about just doing the whole kerdi shower pan kit but 1. I like making my own pan and 2. The main reason, they want a pebble floor and I’m looking to make more of a slope than the 1/4 inch the kit has.
Do I guess my question is. Does anyone else have a good way of doing this without tearing out the bottom 6 inches of drywall and adding extra days on the project??

As typical to every kerdi shower, set your drain then pack your mud bed to the drywall. When finished, kerdi fabric from the drain to above the shower head.

For when DIY isn't such a good idea...

As Paul said, you have no issue at all! That's how a Kerdi shower wants to be built. The drywall is never going to get wet again, the mudbed is never going to get wet again, there are no issues at all. Remember, there's no liner at all, just the Kerdi drain, and Kerdi fabric.

It's a DRY heat!

Okay just wanted to make sure 100%. Ive only ever done them one way or the other. Either used the entire kerdi kit or did my own dry pack with a vinyl liner and waterproof with another product. I just found a video by schluter that shows the dry pack. I will be using the metal lathe underneath as well.
Thanks for the replies

Yes, put down some poly or felt paper first, then the lath.
