I don't have that engine but I have inverted the roller on one of my engines. When I did this it would contact the cam on an unused part of the roller. It's worth a try.
Heat shrink tubing isn't going to make the roller round again and it would change the diameter of the roller.

Light groove doesn't really matter, except to the extent it changes the pick-up point. That can be readjusted. You can always replace the rubber roller, y'know. They can't be that expensive.
How about looking for a brass or aluminum rod the correct diameter and cut a piece to fit. Should work for a loonnnggg time. I have the same roller setup but mine is still un-grooved...
