Albeit I am not aware of any concrete solution, I wouldn't be pessimistic at all. It may be *much* easier than unbaking the cake. Well, to some extent, it would be unbaking, yet such unbaking stuff is state of the art at least in image processing these days. Usually it's a piece of cake to unblur unsharp images and recreate clear, crisp photographs from otherwise potentially motion blurred images. Wouldn't be surprised if some audio engineer created some sort of inverse reverb filter for generic recordings.

If reverb was engineered by some plug-in, it's virtually a given that the corresponding inverse reverb would yield the original signal.
