Engineer wars.
Everyone is class locked to Engineer. There's three lanes, one with a main KOTH objective and two side lanes with robot factories. If you cap a robot factory your team can feed it metal to create robots/sentry busters to try and break through enemy nests. If you cap all three points you win instantly because it's pretty much over for the other team.
KOTH is essential for this because games would be endless otherwise, but you could use an extended timer if you want the full meme impact.
