The new Hyperion's system doesn't require 0-flux, it requires the zero flux boost. This means that with Elite Helmsmanship you just need to put your shield down and hold your fire to teleport at any time. This does, however, have the issue of making elite Helms a must-have skill in order to use the Hyperion to its fullest.
I suspect the AI won't be smart enough to do that, but I give them SO anyway so it's not a big deal.
New Hyperion is pretty overpowered honestly. I had originally thought it would be gutted when I read the patch notes, but it carries my endgame fleet, and the AI does better with it than any other frigate (AI in general is about as dumb as a box of rocks, but it still gets something done).
One thing I did notice, I'm pretty sure old Hyperion's teleport made it instantly untouchable, like a phase ship entering phase. New Hyperion is vulnerable to damage in its original location until it fully vanishes. Might be vulnerable in its destination too but that's a little harder to test. In any case it means that I have to fly out of immediate danger first before teleporting away unless I'm willing to take damage.
