Sorry, I had it wrong: - playing with the straddle cable length - I believe it's a shorter straddle cable that gives more leverage (details on Sheldon Brown's web site)

Should be:

- longer straddle cable that gives more leverage (more brake travel per lever travel). (You use a shorter straddle cable to make the brake more powerful (but with increased lever travel). -- Jan Heine, Seattle Editor/Publisher Vintage Bicycle Quarterly http://www.mindspring.com/~heine/bikesite/bikesite/

700c rims are 4mm smaller in radius than 27" rims. So, if the studs are properly located for 27" rims, they will be 4mm too high for 700c rims. This will make the pivot point too close to the rim, making the brakes difficult if not impossible to setup correctly. And it will significantly reduce the pad travel for a given cable travel.

I'd stay with 27" rims. Sun still makes the CR-18 in 27", which will look fine on a period bike.
