this is something I search some time ago and I don't thing there is a way to do it as we what to.
You can call form in revit but the user will be block until you will end up a ExternalComand, I know that in older version of revit some one was able to do it:

but how J.T. said it was illegal.

and with out Revit there is no way to create or edit families.
