Repairing core memories....

So I have these 2 PDP-8/L core stacks I am trying to recover:
One would be perfect, if bit 3 @ adr 0 would be alive...
Although this is 99.99% OK, it is of course not good enough.
The other stack seems to be a total loss :
2 sense wires are open circuit, more than 20 select diodes shorted. Of course the further quality of the cores is unknown.
Is there any realistic way of getting one fully functional stack out of these ?
Removing a single core from the really bad stack to the almost OK stack would seems almost feasible to me, since address 0 is bound to be on a edge of a core mat.
Any ideas / suggestions ?
