I don't see why it wouldn't work OK. Not sure what gearing you have, but be sure it is low enough.
BTW, 50 pounds of gear is not light touring by most standards. People are all over the place in their packing preferences, but... I would suggest shooting for 30 pounds counting panniers, but not food and water. If you wind up with over 40 pounds I would look long and hard at the list.
It is possible to get below 15 pounds and still include camping and cooking gear, so 30-40 pounds shouldn't be to hard to get down to.
