Is Resonance what let Zenos wield his enchanted katana?
-Probably not. Even during the duel with him in Rhalgr's Reach, he was already using the Storm and Swell to produce lightning bolts and bursts of wind. I don't remember where, but one of his bios mentioned he was already augmented before the events of Stormblood; assuming aetherial conductivity is necessary to wield enchanted katana like Zenos does, Aulus probably made that possible for him.

Side note: though he uses the same weapon(s), Zenos fights nothing like a SAM unless you consider some of his techniques to be hyper-augmented versions of SAM abilities (Storm, Swell, Sword being a massively enhanced Midare Setsugekka, f'ex).
You do raise an excellent point in regards to Krile (I mistakenly remembered her kidnapping being earlier than it actually was). The other augmentations would make sense as well. I wonder if we'll get more elaboration on the nature of what kinds of stuff he went through in the future, in the light of recent events. Probably not, but it would be interesting to get some more background at least.
