That’s a very nice donor bike. CK and everything.. Rolf wheels are some of the only ones approved for tandem riding, so you could use those, but IMO the current ones look better.
I regards to gear, you’ll get a very high gear if you swap the group. You can’t stand up and cycle on a tandem, so you need spiny gears. Look into a 1x setup with a wide mtb cassette on the rear and a trigger shifter.
