It will depend on how deep the handle channel is cut. When whomever you commission to change the wrap removes the linen, they will be able to see if the leather wrap will work without changing the channel in the handle. I have a Tascarella that had an irish linen wrap and I had Kenny Koo replace it with a very thin, smooth european calf wrap, and no alterations were necessary. As Sam said, the thickness of the leather will make a difference as well. The thinner leather provides a better feel in my opinion, almost like a wrapless cue
