Good point about the 27" to 700c conversion. My Univega Viva Sport originally had 27" wheels, and now has 700c wheels. Plenty of adjustment on the standard reach brakes, and it now has room for at least 35mm tires, maybe 38.
I've had a bunch of 80s road bikes, and have yet to run into one with a bad headset, but YMMV. 80s MTBs on the other hand... well, they often lived a harder life. Finally, the OP is looking for a Roadini replacement, but mentions the Trek 720. The 720 is a pretty serious touring machine, and not really comparable to the Roadini. I focused in on the Roadini part, and as such, was suggesting 80s sport touring bikes.
