They are both great bikes!! When I bought my XT660X I also asked if I could purchase a 21 inch front wheel and then swap the wheel if I wanted to go off road. Unfortunately the answer was no, you would also have to swap the front forks so I forgot about the idea. Would be nice tho.......and ideas????
