As a conditional item...

The winners from the earlier event go to the later event. Once a winner is crowned for the second event, the first event winners join them on the field. Handshakes ensue, followed by best-three-of-five. (Such great teams, must see more of them.)

The conditions?
--The earlier winners have to travel one week later. If any one of them can't do so, the plan falls apart. That means this is probably a non-starter.
--Vary which event is the "earlier" event. This might be tricky, but necessary to prevent one being viewed as "easier" or what-not.
--There can only be two championship events for this--beyond that, it gets tricky.
