Don't think it can happen. Vector is reluctant in converting full size to mini's.
The problem is when they converted the full size to mini, they cut the receiver, weld it, then heat treated it to last a lifetime.
If they were to take a current full size, they would have to treat it to take the temper out of the metal, cut, then weld, then heat treat it again. They are not sure what kind of life the metal would have left after undergoing all the treatment.
That is what I have heard second hand.
