Well, I have a set of factory 14” road wheels on a set of 11x2.5” brakes with the finned style drums, but I don’t know specifically about 14” rallye’s.
The outside diameter on the finned drums is 13.62” at the widest part. The 14” rims I have on there are pretty narrow, they’re just a set of rollers for me, so it’s possible a wider rim with more backspace might not work. You’ll have to measure the inside clearance on those 14’s.
