Quatre Knight Aces Pre-Season 4?

[Hope]

In their flashbacks, we see the Quatre Knights fighting with their current legion units.

At first I was like, "Oh right legion during the Link Joker invasion..."
But then I was like, "Legion during the Link Joker invasion??"

I am assuming that Legion didn't exist prior to Season 4 of course since if they did, I'm pretty sure they
would be talked about a lot as champions from other circuits use them.

I'm hoping I'm not missing anything and that it's safe to assume that during the time of Season 3, the Quatre Knights used the same ace units,
but rather than being Legion units, they had limit breaks..

- So the questions is, what are possible skills for these units?

I think Fianna at least would have had the same first skill, maybe with CB1 & SB1 instead, as well as having the run-of-the-mill CB1 +2000 skill that we all know and love. Sin Buster would have been the same, with a second skill that gives it +5000 power by discarding a card on-attack. Not sure about the other aces, though.
