Insane 2MPC idea

Theoretically, after round 53 on CHIMPS, you have popped 40,553 Bloons, less than the amount of Bloons required to still get 2,000,000 on a newly placed tower. You also have earned just enough money to buy Lord of the Abyss and place a boat in it's range in order to get a boat 2MPC on a map without water. This is probably easy on an easy custom map, but has anyone ever done this in a real game?
