I certainly don't know anything about framebuilding, but I imagine there is a chance a 70cm Valite frame might have some desirable and hard to find attributes.
I've done some reference work on Valite. It is a cabon steel that has the usual Manganese and Chromium in less than 1% quantities. Valite also have 1/4 % Vanadium, which removes inclusions.
Inclusions are non-metalic compounds that reduce the alloy's strength.
