An alliance? Perhaps an autonomous region that is loyal to you, but runs the day to day operations of its government? Would that be agreeable, somewhat like how the states are to the United States, you are Uncle Sam, and I am a sub section of that.

That works for me. We just need a player(s) controlling Washington and/or British Columbia, then we have ourselves a Pacific Alliance or Pacific States. Something like that.
