I'm not in the exact same situation as you as i don't own retros of my 1991 BW leathers (they never released that's why), but I can guarantee you that i'll wear to death my '91 after soleswaping them, soon or late.
I see vintage AMs like an opportunity to have better AMs than the currents, because they are the OGs, the shape, the comfort of the upper (having tried on vintage BWs and 95s and current BWs and 95s, i can guarantee that there a difference with the upper's comfort, more padding,the shape follows the foot's shape, remember that the OGs were running shoes),etc BUT they need to be functionnal, so a soleswap is necessary
I don't buy vintage for display, it is for me a waste of money...imo
