Have you tried the ODI Ruffian grips, maybe those would work for the WOT problem. I can't really find any dimensions, but they look thinner in the picture.
I don't use fat grips but I have used all the major brands and styles of finger throttles and always been able to get WOT. When I built my Big Red GSX I remembered how my finger and wrist get tired during races and long rides. I actually removed one of the carb's return springs for less throttle tension. I don't recommend it to others because if the linkage pops off one carb wouldn't self return.
When the stock throttle action becomes stiff it is usually a build up on the throttle shafts.

Diameter: 30mm
Length: 100mm, 130mm or 143mm
Bar Ends: Snap-in end caps included
