Suggestions for new event formats

We’ve gotten 3 on 1 fights. How about 4 on 2 fights? This could be like a new pve. So maybe two bosses to fight but we could use 4 characters. Rulk with switch, im40, and flaptain! Flatain uses the red, Im40 uses the blue, Rulk uses the green, flaptain’s blue reduces countdown tiles for IM40 and switch. So many new strategies you could come up with using 4 characters instead of 3!
