I wonder what happens if you build Sion up to over 100,000 health and Yorick's ult expires on him. It does 100,000 true damage. Does this mean Sion would still be alive when the effect expires? This obviously isn't feasible in standard games, but would still be fairly awesome.
Yeah, I dunno if there's a way to bypass it some way. I think it is more than true damage, it's fountain kind of damage, I don't think you survive even under Kayle/Trynd ult, though I'm not sure these abilities can be even used. For Sion though, since his health can go over that, it might work. Still, I think there's a time limit to games. Every montage I've seen featuring really high stacks for Nasus/Veigar/Sion/others ended by a crash at some point, also minions get so much resistances they become basically invulnerable.
Someone farmed Nasus stacks for a while and the game soft-locked after something like 70k. I doubt the game would handle 100k health (whether it be the actual value or the time required to get to that value).

Works on the clone, but weirdly they didn't try to see if it worked when Sion actually died with ult on him.
