Although it technically fits it's probably not a reasonable build option since there is a good chance of direct thermal contact to the capacitors on either side. This could be rectified in the production version by moving R3 down, turning it 90 degrees clockwise and moving C3 as close to the board edge as possible. This should gain you at least 3mm that can be used to provide reasonable space on either side of the heat sink.
I may agree about the heatsink over the board. Looking at my build there is ~1mm of clearance on either side of the heatsink to the caps. These Mouser parts may be OK for off board 532-581202B25G, 567-634-10ABP
However, moving C3 around is not as feasible as you make it out to be. The cap in the picture is 16mm, but if you use the heatsink facing off-board, there is room for an 18mm cap. Most I can move over an 18mm cap is 1.5mm (to maintain clearance around the mounting hole and diode bridge) - and that kills R3 totally.
