Yes, you would have a hard time fitting P50 fenders under Tektro R559 sidepull calipers. R559's will even intrude on P45 fenders and will bend the nose of the fender into the tire when the Q/R is opened.
A Sheldon nut may help you, or may not. It would rotate the fender towards the rear, which would reduce the length of the nose (and make the mudflap closer to the ground). But I think that there still would be enough nose for the R559 to bend it. Drilling a hole and fixing the nose of the fender to the Mark's rack will definitely make it more secure and resistant to the fender-bending nature of the R559. I swapped the R559's out for centerpull brakes (I used Paul Racers I found on this list) which have much better fender clearance.
