Game Director Jeff Kaplan recently addressed this possiblity in another thread yesterday:

exceeding 12 players per match would cause significant technical challenges (we’re highly optimized towards 12 right now). experimenting with less than 12 is more realistic. it’s not that we cannot do it… it’s that the cost would be extremely high.
