An Idea for a New Summoner Spell

I think an awesome idea for a new summoner spell that could create some diversity in the meta spell picks (TP Top Laners, Exhaust Supports) would be one that resets all aggro from entities that don't automatically target a champion.

For example, you just won a level 2 fight in the top lane and are now getting destroyed by lane minions and could die to their missiles. You use the summoner spell and they all stop attacking you and go back to their default targets; your allied lane minions. Another instance would be a 2v1 tower dive. You take the tower aggro due to your jungler's misplay and are most likely going to die before you can get out of its range. You pop the summoner spell and the tower stops attacking you and goes back to clearing your minions until you or your jungler picks aggro back up.

I think the spell would have few uses but maybe they come often enough for the spell to be useful or maybe the added security opens up new opportunities and leads to more aggressive dives.
