A Kirkey Intermediate RR would work well, mounts very much the same as your drivers seat, and is not expensive. Add a 6pt harness with clip in subs and laps and it can be in or out in about 10min. About $400 new. The least expensive FIA seat I'd recommend starts closer to $600.
A 16" width will comfortably fit all the instructors that I know.
I think a HR seat on the passenger side is overkill since you'll be getting instruction in a HPDE session at less than 10/10ths, the HR wings on the passenger side can block the drivers visibility, and if something does go badly your instructors will not have practiced exiting the car in 10 seconds.
My son has a "new" (in quotes cuz it has been sitting in the garage for 2 years) Kirkey seat with cover that he might be willing to sell reasonable. Never been drilled or modified. If interested, let me know and I will contact him. I think we also may have some bracketry.
