Few crazy ideas about the Frozen Watchers (pre retcon ones )

I just had a random idea during this whole Neeko hype about the Frozen Watchers and how they can still exist in the current world of Runeterra. What do you think if the Frozen Watchers (not the void ones )the yeti like things with frozen horns were some extremely intelligent beings that exist far far far in the north in the unexplored areas of the map. And they are creating their frozen army (kinda something like the night king from Game of Thrones) and are preparing for a invasion but are somehow sealed in the lands of endless winter. Or they were like the very first things before Ornn, Anivia etc. shaping or creating the world and somehow they got corrupted by the power they wielded and maybe overspread ice and winter then they were pushed and thrown over the Frejlord and trapped somehow. Or they could be simply True Ice it self. A begins of the very magic it self. Begins that are as old as the first true ice and are the ones that spread it maybe. Or They are some ice beings that are able to control true ice but aren't able to set foot on land with out ice. And they existed way before humans did and after humans appeared and fought and the remaining ones fled to the lands in the north and wanting to reshape the world in ice. So they could never be limited to a land where its only winter if the whole world is in a endless winter. I don't know they are mostly GoT inspired ones, but I really don't want them simply gone they have such a cool design its sad if they just go to the bin. I just wanted to see what you think of these ideas and maybe tell me some of your own ideas about how the Frozen Watchers can still be a thing in Runeterra.
