Has OP considered upgrading to forced air? with AC?

Since code will almost certinally require insulation in a full gut
job, and moving all those radiators

How old is the boiler?

First, why are you asking me?
Second, since when is forced air considered an upgrade to hot water?
Third, it's a rental which may not warrant central air

. . . . . If the place is a gut job, I'd definitely have the HVAC
contractor cost it out both ways before I made a decision.

Since the place is now completely gutted, I may do that. I trust the HVAC
contractor that I usually use, so it may be worth another look. But, my
hunch is that trying to run central air duct work for this 3-story property
may not be worth the cost and effort involved.

. . . . Do they still do those systems with tiny high-pressure ducts, for
retrofit to steam/water heated places?

Yes, they are still available.
