That would be a major change to the entire bike. In reality, I have room for maybe 700c x 44 tires on this frame without fenders. 700c x 35's is a good sweet spot for road/occassional gravel. Remove the fenders, swap out the tires, I've got a really good gravel bike. The only thing missing would be disk brakes for long, steep downhills, but I've got a bike for that already.
