Has any thought been given to a system that emulates the Regen Globes from HotS?

Regen Globes are the game's primary lane sustain mechanic. They drop off specific minions, mercenaries, and other events, and restore some of your health and mana over a duration. Zoning your enemy off their regen globes can let you steal them and take a lead in laning, and some quests revolve around collecting enough to complete the condition.

I have to wonder if such a system could be adapted to League. Maybe something like Cannon Minions drop a Regen Globe that restores up to a set amount of health and mana, based on your missing health/mana. This could make laning advantages more pronounced if you can zone your enemy off their globes.

But this is all theoretical, of course. I'm just curious if Riot has entertained the idea.
