Sure, but what is the point in that? You will always install the newest versions, so they will come from the non-subscription one (or test if you also add that). The versions present in the enterprise repository are the same in the other ones, but most of the time a lower version number, so therefore the newer ones are used. You can lower the priority of the non-enterprise ones, but then again, what's the point then?
