It might spice-up the whole match to have this final-someone's-gotta-win tiebreaker before other tiebreaker matches, and then hold the result "in case it's needed". That'd be in the same spirit as this recommendation to have Soccer penalty-kick shootouts before overtime.
That is: you know who will win if all other tiebreakers draw, giving the side which didn't earn this final-tiebreaker the knowledge they have to be more aggressive, much earlier. (In the extreme, you could play this before every other match.)
