Maybe, but I doubt it.

Since every time a new magical element like this is posited, the obvious thing to do is ask how someone like Quirrell could abuse it, I'll note that Canon Voldemort was capable of instantly creating a better-than-new magical prosthetic for Peter Pettigrew after the latter sacrificed his hand for a ritual.

Limb farming his own Death Eaters is thinking too small, particularly since the prosthetics might be identifiable. I'd go with "Imperius innocent civilians into casting the ritual for you and then memory charm them so they don't notice their limbs have been replaced." Although maybe you don't need to replace their arms, since even when they do find out, what are they going to do about it, really?
