What if Bard retconned the League?

Note: This is 90% a joke thread. I kind of got the idea in my head, played with a bit, and I want to shoot it out. This is not intended to be a super serious discussion, and please don't bring up any opinions on the Retcon itself.

But yes, as the title said, what if Bard retconned the League? From what we know about Bard, he is a powerful spirit, one who roams the cosmos, and only enters Runeterra when it is in the gravest danger. So I mused on that a bit, and it just sort of hit me: What if Bard saw the League as a great threat? Maybe he saw that there was a huge problem in a place that forcibly dragged Champions from other worlds, that bound spirits of the earth and the Void to their bidding. Maybe he saw a future where the League was out of control. So he snapped his fingers and made it like it never was. Problem solved before it even started.

Now, obviously, there are some potential issues here. Most notably, we have no way of knowing how powerful Bard really is. An action like this would easily be Omega level, a being capable either of manipulating time or direct removal of an incident. But I'd like to leave that aside since, like I said, this isn't meant to be a super deep thing. Unless you guys REALLY want it to be.

Anyone else have any thoughts on this? And please, keep it reasonable. Even I can't really respond to "OMG THIS IS SUCH A HORRIBLE IDEA IT MAKES NO SENSE YOU FAIL GOOD DAY SIR."
