Well, if you're halfway and outside of hte event horizon... I don't know. But you definitely can't escape an event horizon.
I don't know what would happen if two event horizons overlapped briefly, as two black holes passed by each other at significant speeds. That's definitely above my paygrade :P
Well imagine you are X distance from the singularity, and time dilation is hugely slowing down time from an external observer. As blackholes approach each other, the distance between the singularity and the event horizon significantly decreases. They become kidney shaped before the blackholes merge.
The trick is can a blackhole approach quickly enough to catch you as you keep dropping as you past horizon. Normally I'd say no, but the time dilation significantly complicates things.
