Some complex libraries needed special porting (eg. NumPyPy), and there was work under way to get rid of that and provide a CPython compatible interface.
The CPython team does take clues from PyPy (eg: see the CPy3.6 dict implementation), but they are also a lot more careful (some might say "slower") to adopt changes. Both teams also seem to have some ideological differences on how to face the long term development of the language (usualy, GvR goes for "simpler" instead of "more performant").
