1) Mirrored it 1 to 1 (blocked zones 2, 6, and 4 with Guard Towers) in the center, with 2 portals on another plane.

2) Reduced version (divided the template in half and mirrored it, with 2 portals in the center).

I'm just not sure if Guard Towers are needed between the planes. If they are, what size should they be? But it's probably better to have them than not, because without them, you can clear out two thirds of the map in one turn. But it needs to be tested.
I was also thinking of making one for 8 players for a 4v4 game (it might be useful with the appearance of lobbies and Online Hotseat), but the generator still sets it to 4 players. If needed, I'll work on that version too. It will take more time.
