I think the short answer is: for now, don't do that.

There was some discussion here about conflicts:

https://lists.gnu.org/archive/html/guix-devel/2018-10/msg00384.html

We basically agreed that for now, we should error out if there is a
conflict, but I don't know if that code has been implemented yet.
