Probably not such a great idea, since you aren't in control of any
updates that might happen to the User model. It's the standard problem
that if you change Django's source, that's fine, but then you have to
remember to make sure your changes work with any updates we might happen
to make to that code (we aren't about to add any new fields or anything,
but extra Python code might be added, for example).
A better approach would be to create your own many-to-many lookalike
structure by creating the intermediate model with foreign keys pointing
to User and whatever else you want (I guess also User in your case).
That model is entirely under your control and won't require changing
Django's source.
