Inspired by this analysis of a human (OK, Captain America) hitting water feet first at terminal velocity, I'm wondering if supercavitation would be possible and whether it would improve your chances of survival?

Would a human body reach a high enough speed to supercavitate on impact? Would this reduce the g-force to a survivable level (eg by allowing deeper penetration into the water)? And crucially, when the supercavitation collapses do you still have to deal with an unsurvivable acceleration?
