I don't see how it would help here.
Copying the CPython Lib/ directory is not difficult, even though PyPy made
slight modifications to the files, and even without any merge tool.

OTOH when PyPy changed minor versions (from 2.7.0 to 2.7.2 IIRC) most of
the work was to follow the various tiny fixes made to the built-in modules:
_io, _ssl and _multiprocessing.
