Baron-like buff for teams with dc/afk players

What if Riot implemented a non-transferable, scaling buff (a la Baron) that would kick in when a teammate is dc'ed or afk? I play mostly ARAMs nowadays, and something like this would help greatly. I imagine it would help on the other maps as well, but it might even make people rage/troll less knowing that it's not a completely negative experience and 99% of the time, an auto-loss. Since you're going to penalize players that wish to exit the game after someone leaves (wasting time), why not reward the players that stay and play with a buff?

I know something like this could possibly be abused, but you just make sure the scaling isn't too much. Losing an entire champion is huge, and allowing players to continue until or passed 15/20 minutes and do well would help curb this problem. Call it "Aura of the Lost", or "Holdouts' Hauberk" or something.

Aside from the toxic player attitudes, the dc/afk problem is the only major problem with this game still, and I think it could be worth testing, even if it's just on ARAMs and Treeline (scaling would be less for Treeline). For Rift, you could even have Baron not spawn so that the 5-man team can't greatly overpower the outnumbered team.
