I can't get a hold of my plumber and I'm hoping someone with expertise can answer a question

We're in the process of converting a bathtub to a shower pan. We currently have a center right drain and our plumber told us to purchase a shower pan with this type of drain placement. However, the shower pan we want to purchase is from Kaldewei and it has a corner right drain.

Is it simple for our plumber to move the drain over to the corner?

If so, can you give an estimate on price? $200 vs. $800.

What kind of process would this involve?

Any thoughts here would be much appreciated! I do not want to make a wrong move. Thank you!
