What size freewheel will the hubs handle? Welcome to the forum, if that's not been said.
I agree with those who say "too light for CX."
Also, a nice wheelset like that would deserve a thorough clean-up, maybe a re-decal, and a nice set of tubulars cleanly mounted.
There are plenty of folks riding older bikes that would clean them up, mount some nice tubulars, and ride 'em, lots.
