I would trust the treated wood not to swell and twist since its been so long and if you plan to wrap the curb with lath and mud it out. I'm not talking about a skim coat of mud but a 1/2 inch mudbed on all 3 sides. You might check out the "shower construction info" thread in the "liberry".

No one knows if the mud and tile will crack over the pipe. That is going to be the weakest point and if it cracks anywhere, I'd say it would be there.

Looks like to me, your pipe (redline) will have to stay full of water for it to stay primed and allow the pump to pull it up and over the curb. I could be missing something but I don't see that happening. If it doesn't stay primed, the water will just run towards the drain.
