I could be wrong, but you can not change semantic of = ( assignment operator )

As for the ==( equal operator ), you can overload == that takes
boost::python::object and then test it for being None.

I am almost sure that what you are trying to do should be rethought.
For example:

x  == None will work, but x is None will not. This can lead to bugs.
