Is there such a thing for converting an old road frame?

The traditional solution was to go to your "local" framebuilder and have them brazed on permanently. It's less expensive than you'd imagine; Marinoni cycles lists Canti bosses at $20 a pair on their price list for frame repairs (see: http://ourworld.compuserve.com/homepages/FBeauchemin/PRODUCT3.HTM )

Look at racing frames from the 1970's, since they will be steel (and therefore easier to convert) and may have adequate clearance for large tires, especially if they're British, since even race frames from there often had room for fat tires and fenders. Best of all, you can often find them for real cheap, if you don't already have one -- one of my favorite bikes is built around a no-name '70s vintage lugged frame & fork (British or American custom, probably) that I swapped $35 and some mountain bike thumbshifters to get.

While I suppose it's possible, I can't quite picture a bolt-on cantilever boss, particularly one that could stay put on a round seatstay against the strong forces involved in mashing a brake shoe up against the rim -- particularly if your goal is to avoid damaging or altering the chainstay.

Moots used to make "Moots Mounts" a bolt-on canti stud, but they cost more than having a framebuilder braze some on. Although, it doesn't include the cost to repaint or touch up.
I've done this to three or four frames (friends and my own) with great success. Will last as long as the rest of the bike - when done right.
Check clearances at chain stays, seat stays and around both bridges to ensure you can run the size tires you want before investing in the caliper to canti conversion.
I have a side-business/hobby that involves all kinds of frame modifications ie, dropout replacement, rear triangle reconstruction, brake bosses, etc. I've done everything short of building a frame from scratch (currently in the works). I've been brazing on steel frames for quite a few years.
