The Pegasus was originally called the Mercury V, but was “mechanically improved throughout”. It would seem unlikely that any parts were interchangeable.

The main difference seems to be that the Mercury series had a shorter stroke (6.5 in.) than the Pegasus series (7.5 in.). Apart from that, both engines have exactly the same basic description in the aero engines section of Jane’s Fighting Aircraft of World War II.
