Idea for next super mixed event

I really like the idea of party battle. Its makes it easy with only three new characters per side. I think it should be a vanquish match, since roses have the advantage in TT, and because Gnome Bomb was last time. Infinite Ammo so the party never ends!

A few of my own ideas: (I'm a newish player, so apologies if any of these have been done.)

1. Tremors - Chompers vs all zombies. No additional crazy settings. (or simply exploding if there must be one) This one should be gnome bomb, suburbination or TT because chompers have a big advantage in both vanquish modes.

2. Mechanical Menace - Engineer & Imp vs Citron and Cactus. Any mode will do. No healers, Imp and Citron tanks, Cactus and Engineer support. (This would be a better match up if engineer still had the drone.) Speaking of...

3. Dog Fight -  Cactus vs Pirate. Drones and snipers galore. Preferably team vanquish mode, (collecting the orb sorta defeats the purpose of sniping) and for added laughs could add super low health. Sniper battles where one shot means death. Plus, drones become more threatening. (This is even more reason to do vanquish mode, to prevent mass vanquish farming since each match is limited to 50 per side.)

4. Super Heroes - Peashooter vs Super Brainz. Crazy settings: super speed and low gravity. With Hyper, and the Super Brainz built in jump height everyone is a super hero. Any mode should be fine.

5. Explosions! - Scientist and All-Star vs Peashooter and Corn. Crazy Settings: simply exploding. (also super knockback if you want the fun to be turned up to 11) Sticky Grenades, Imp Punts, Shuck Shot and Bean Bombs everywhere! For added exploding fun, why not put it on the Gnome Bomb mode. Overtime will be a blast!

6. Song of Fire and Ice - An elemental battle but limited to fire and ice. Freeze or Burn, you decide. Simple, but could be a lot of fun.

7. Toxic Waste - Toxic variants only. It is and exclusive club but should make for a fun event. Suburbanation and TT seem like good fits since they require players get close to each other. For this one why not speed things up with infinite ammo to keep the toxins coming. (Could also do super speed for more laughs.)
