Idea for a future Champion ability: A trap that creates "Broodlings" to attack enemies

When looking at the current traps (Caitlyn, Jhin, Teemo, Nidalee, etc.), they all share something in common: they do damage themselves. But I have an idea for an intriguing twist on the standard trap.

What if we had a trap that, once triggered, released a small group of "Broodlings" that attack the closest enemies they can find?

This could fit so well on a future Void Champion, providing a unique trap that can have high damage potential, but isn't as instantaneous or damning as, say, a Teemo mine (which can spell your death if you hit one when you're too low).

Here are a few details on said "Swarm Mine" that I'd have to highlight.

• The Broodlings created by the Swarm Mine are very fragile, are melee-ranged, and do not cause unit collision (so they can't body-box you in).
• Broodlings do not give gold or experience when killed.
• Broodlings cannot attack structures.
• The number of Broodlings spawned would depend on skill rank, Champion level, and/or ability power.
• The Broodlings would be considered low priority by Minions, Monsters and Turrets (they'll only target the Broodlings if nothing else is available).

So, does anyone else think this could fit?
