Determining when an actor is being forced to break through physics blocking?

Is there a way to do this? For example, when a character is standing on a moving platform which is shoving him up toward the ceiling, as this motion continues he will eventually be forcibly clipped through the moving platform and fall. Obviously a special event (killing the character, most likely) is needed in this situation, but I’m not really sure how to DETECT it. There’s no way of determining (AFAICT) the individual vectors of two frame-simultaneous collision events on an Actor.

Any ideas?
