No, sqlite does not belong on this list as it wraps a C library. Plus there is an explicit block for ctypes-based modules in the stdlib which would prevent moving over the PyPy implementation.

And I'm sure pure Python versions of all the crypto libraries are out there, but I would be worried about them being implemented wrong, too slow to care, etc. Plus short of PyPy all of the other VMs have access to those crypto libraries in their own standard library so there is no need to provide it in Python's in pure Python.
