As others have said, as long as there's a body in the right hand seat, then P1 can be in the left hand seat or actually be the body in the right hand seat.
However, unless you've flown (hands on) a few hours from the left hand side, I'd suggest the RHS body would better be a licensed individual. There may be nohing wrong insurance wise, but note two things. One - the references for flight, the scan, the hand swapping required and all the rest are different than sitting in the RHS. Two - the controls in the RHS aren't removable, so an unlicensed passenger in the RHS with a licensed pilot in the RHS may cause the school or the insurance company a few problems.
