I really do not think so, Record cups were nicely ground, Nuovo Tipo for example were stamped.
My bet Veloce would be too and probably not the same diameter and or width.

You might find that an alternate front hub even with your needing to polish it from the beginning will be easier to do effort wise and price wise too.
The cups don't fail very often. Cones first, note they are smaller in diameter so the forces are more.
I would look for replacement cups only if I had the hub already laced into a well built wheel.
The effort to extract the old and press in new is not a minor effort, yes it can be done. You might find it a frustrating adventure.
Part of the challenge is to pull or otherwise extract the existing cups with equal pressure all around, the tolerances are tight, and any unequal pressure will just lock it in, way back we had a customer who tried. We later called Art Stump, who had his special tool he devised for the job, very nicely made of three segments (think drill chuck like) with a rod that trapped the segments and allowed force to be applied.
