I dont see the big problem in allowing a team to have multiple lower tier sister teams, to help take on promotions. Within reason of course.

As long as all of this is declared before we lock down the teams for the tiers etc it should be all fine. And a masters/gm from tier 4, could play from tier 1 to tier 3 (ok they probably wont play tier 1, due to not being good enough, but rules wise its not a problem...)
