Account recovery requires an owner key that was relevant within the last month.
It doesn't exist for lost keys it exists for stolen keys.
I don't think you can recover those keys.
I've blogged about witnesses activating the "reset" account feature, but that isn't a thing yet and may never be... and even if it was: probably wouldn't work for you in retrospect. Sorry to be the bearer of bad news.
Ah damn thanks lol
