AZ Plumbing Question

[VDIY2015]

I plan to convert a tub-shower space to a tiled shower on a concrete slab.
1) Can I cut/remove the existing drain shoe at any one of the locations identified in the picture and use a Fenco coupling to join another 1 1/2” pie that will attach to a 1 1/2” to 2” converter for the shower drain?
2) where would be the best place to cut?

Showers normally have a 2" drain and p-trap. You may have the 2" lower down in the dirt. I would dig it out more and see what you have there.

Thank you for the guidance.
