Map Settings for variable numbers of players

In ES1 I had a regularly scheduled multiplayer game, however some weeks someone couldn't make it and we had an odd number of players... with no maps to support it fairly.

Have a variety of map types specifically setup for odd numbers of players and not have 'empty' constellations or starting spots for players not in the game.

Specific requests:

Spiral 3, Spiral 5 & Spiral 6

Tri-Elliptical(for 3 or 6 players)
