Might not be the nicest solution, but works here.

You can do some magic too:

from zope.interface.interface import InterfaceClass
newIF = InterfaceClass(name=newname, __module__ = module,
                           attrs=newfields)

Where newfields is a dict with keys of name and values of fields
(deepcopied).
