Essentially that's what Agent Smith does in the Matrix sequels. He can't "escape" the Matrix, but he can basically make it his own. (For the purposes of this analogy I'm intentionally ignoring the ridiculous scene where he somehow transfers himself to the physical world.)

Interesting to consider: if we ever discovered ourselves to be living in a simulation and attempted to do something about it, would the simulator simply reset the simulation (a la The Matrix trilogy)? Or would the simulator be intrigued by our self-awareness and allow the simulation to continue?

But anyhow, that's enough of a digression for one day.
