Not really. They will die off and the stocking will come back to an equilibrium with the tank again. Expect to lose around 800-900+ guppies in the next year since the tank cannot support the stocking level you reference. These things have a way of balancing where the overpopulation will die off until the tank can support the bioload again.
You could sell most of them and make a little money though. Even at $0.50 or a $1 each you should see some nice returns!
