NO it is not OK.  IF the fingers of your gloves matched the fingers of you figures hand EXACTLY in EVERY way then it would be ok to conform the fingers of your gloves to the fingers of the figures hand. BUT they do not and never will match with the fingers of your figures hand, They are resized larger and shjifted to boot and in order to bend correctly they will have to have different centers for the finger joints. 

You go ahead and do as you wish but you will find that they will never conform as you wish. The only part of the gloves that you will be able to get to conform correctly will be the hand,

You will have to change the names of the finger parts so they will not try to conform, but keep the hand. I cant explain it any more clearly, but the Fingers of the robo hands will never conform to a different sized and positioned figure, and that goes for any conforming figure ever built. If you cannot have the centers for the bones in exactly the same place as the donor figure because of size differences, then you cannot conform them

You can conform the hand, that should work fine for you, I dont see the problem.
