I'd be down for this! I tinkered with the idea of a Planeteers game and making one of the kids themselves be the vessel and have the combined power rotating between them so we'd essentially have female and male representation of the hero. Never got of the ground though. I'd be interested in tinkering with an additional element.

EDIT: Going over the rest of the OP, yeah... this will be awesome. The only element/power I wouldn't be interested in is the Heart. A Lancer or Big Guy role, or even a combination of the two for a 6th man, would be my choice. Wood or Metal would be cool.
