I think it's a cool idea, but I think it would take too long to have one match. Personally, I would be more likely to try out a 9v9 metagame.
A concern i have with this meta is that the increase in teambuilding difficulty will discourage a lot of people from making teams, which will limit it somewhat. Sounds like a fun metagame though hopefully
Both of these posts sum up my feelings entirely.stall vs stall, i can see me wanting to murder myself now, it could be very interesting though
