I had an idea to create a map template similar to "Tie-break" - a mirrored M-shaped map with one zone, a couple of villages, and a lift to the opponent.
Until a certain time, players can develop in their own area (they cannot go to the opponent), and when the deadline arrives, the red player enters the lift, and the blue player attacks him. Whoever wins the battle wins the game.
With short control and Order of the Phoenix, I think it's quite possible to achieve a game duration of no more than an hour or an hour and a half, while the result depends on skill.
