My personal opinion is that although SCS has to maintain a slightly more traditional and formulated role, spicing things up with some experimentation couldn't possibly hurt.
Truth is the game can become pretty stale after a while, due to the limited content, and us being especially limited to only the (admitably few) 2v2 DM maps can make things even worse. I think we should definitely try adding Labyrinth to the map pool. Sure, it revolves around a vastly different strategy but even DM maps promote specific ships and strategies albeit to a lesser degree.
If people dislike the idea, we can always just remove it and never discuss it again. If people do like it, however, we could even experiment with throwing Scrap into the map pool, with the extra 2 ships being neutrally piloted to the never-visited corners of the map, far away from the action. Hazard and Firnfeld's size (and them being DM) make them too far-fetched to propose, but man can only hope that muse eventually makes a 2v2 variation for those.
Until then, though, I think we should make use of whatever we have available to keep the event challenging and interesting both to play and watch.
