But would I have been able to remain IFR to circle those landmarks if
I asked, e.g. "Request clearance to circle XYZ at 2500, right turns"
and said nothing about altering the flight plan?

Yes! It's like any other deviation, except it's usually more fun.

I always tell the passengers that I can ask, but ATC might need to
deny the request.

With that understood, I request it this way, "I'd like to remain here
(or "over XYZ") for about 5 minutes for sightseeing."

I've always been happily accomodated, once with a "After maneuvring
fly heading XXX," and always with a "Advise back on course."
