Again its a check the insurance job.
It may be that the person being checked out cannot be PIC without being checked out.
Also as well don't underestimate the problems of recovering stuff in the RHS if you are not used to it. You won't be the first or last to grab the nearest engine level to you and instead of full power all you will get is mixture rich. High hour'd instructors get the same problem sitting in the LHS. It used to be weird doing the pilot companion courses teaching in the LHS.
I am not saying don't do it just be aware.
