Plumbing – Drain pipe blocking shower installation

plumbing

I'm in the process of removing an old bathtub/shower and replacing it with a walk-in shower. The problem is that a 1 1/2" drain pipe that was once covered by the tub is now eating into where my new shower floor/walls will be. I'd like to redirect it through the bottom plate of the wall, but the wall is flush with a floor joist that's already been notched and strapped. For some reason there's also already an unoccupied notch in the bottom plate.

Here are some pictures:

What are my options?

I would add another framed wall, adjacent to the one that's there, that's just 3'0" high (except for where the drain pipe runs to the ceiling). This would create an in-shower ledge that's 4" deep...great place to put shampoo bottles, etc. One could also create a between-stud nooks above the in-shower ledge. This idea, of course, would have me bring the shower forward to retain dimensions.
