The minimal change for stable branches would be to add RCONFLICTS
on python{,3}-pycryptodome to python{,3}-pycrypto.

In a stable branch changing what users get installed is not really
worth it for a tiny bit of improved testing coverage.

Based on what you wrote, for master the best solution will likely 
include removing python{,3}-pycrypto.
