This is a problem most of you would hate to have, I'm sure

I have an ~85 bianchi eco pista w/ campy parts.
I also have an '07 raleigh rush hour pro w/ nice modern parts including mavic ellipse wheels.
The raleigh frame has a hairline crack at the top of the seatube, and raleigh will not warranty it.
So I don't ride it.
I'm hoping to get another vintage track frame, and to move the campy parts onto it.
Would it be terrible to then run the bianchi w/ the ellipse wheels, and some non-period other parts I have sitting around?
Or wait until I round up some more appropriate parts?
