Curbless shower

I demolished a bathroom which has a concrete subfloor and the shower pan is 38x38x4 inches deep.

I'm considering a Kerdi solution but I need to raise the shower pan in order to achieve a curbless install. Two options I could think of:

a) Mud deck + Shower tray (Kerdi shower tray is 1 1/8 inch deep)
b) Mud deck + Kerdi membrane

I scanned the internet but find no installs that allude to installing a kerdi shower tray on top of a mud deck. Of course I can't think of a reason to preclude such an install.

Given the two options what's the recommendation?

Option b) is essentially an all mud deck solution 4 inches high with preslop pitch of .25 inches per foot - at least that's my current thought based on internet research.

Also should I put a pan liner between the concrete and the mud deck given I'm using a kerdi solution?
