technically they'd still live in on in the form of their current skins...like Captain Gangplank.

Also, while it seems unlikely now, when the lore is finally stabilizied and every old champ has been updated (which will be the case in about  2-3 years...maybe more), they could actually do that...simply because by then they'd be running out of options to make the game more interesting
