Here are some resources that might help make this tricky issue more clear:

An object traveling faster than light (such as a tachyon) could indeed escape from an event horizon because tachyons travel along space-like geodesics.

As for calculating the probability of a warp drive forming spontaneously from random particles, I'm not sure that can be calculated because we don't know how to construct a warp drive and therefore don't know its required size, density or other such parameters.

*is*a way to make black holes evaporate more slowly or even stop them from evaporating altogether: increase the spin or charge on them. When you reach a certain point, what you have is an "extremal" black hole that cannot radiate Hawking radiation and thus does not evaporate. Reversing this and making a black hole evaporate more quickly does not seem to be so straightforward.As for calculating the probability of a warp drive forming spontaneously from random particles, I'm not sure that can be calculated because we don't know how to construct a warp drive and therefore don't know its required size, density or other such parameters.
