First crack at pfest, just to see whether I could do it.
Verdict: Yeah, I probably could, on a lazy weekend with nothing better to do. Quit after just over 500 rounds due to lack of time but I wasn't even remotely in danger yet and I don't think doubling the damage would be quite enough to kill me.

The problem arises, once your HP regen can't compete with the minor damage anymore. You already used health draughts which implies, Regen alone ended up failing to do so. Melee is so slow, you would need to cure way too many times per round, and things would quickly be very annoying to play.
That said, you can always Fus Ro Dah to mitigate this to an extend. If played correctly, and you have enough attack, you can get rid of 3-4 enemies before they do anything, though the rest will still nuke you as normal, as enemies recover MP and Spirit during stun as well.
Also you used quite a few mana potions, some spirit potions and weaken. That's not a good sign for the first 500 rounds. Well, provided the entire thing isn't supposed to be a pain and you wanna gain something. That's only getting worse.
That said, a full pfest is generally not very worthwhile as 1h. And not without max Crystarium either. Doing a few hundred rounds while chilling is the best way of doing so, if you have some stamina left after arenas. But for that you'd need to get away from weaken.
For me personally I feel like pfest gets too cure heavy (outside of short bursts of bad rng) once I hit around round 300-350, This is where a draught helps, or some occasional weaken on a few enemies of a 9 enemy round, with a just used up cannon. Alternatively Fus Ro Dah, that you can use every round, but requires more active care. That's why the "lazy" way of doing it, is stop around round 300-400. Obviously everyone is different there. Takes about an hour for me, which lines up with RE. With more attack this can also be faster, but nothing beats a mage.
