I did exactly the same thing a few years ago. One of the best mods I ever made. Even with the winch moved, I still hit the roller fairlead on many occasions.
I have since switched to synthetic rope and a hawse fairled (WAY better clearance than a roller fairlead) and have only hit it a couple times.
You can use a Hawse fairlead with cable (I think), so that is an option if your friend is looking for more approach angle.
