Who's who as a legend passive?

If you're familiar with Who's who from Black ops II Zombies. Once you go down, you turn into a ghost out of body, and you can either revive yourself or keep running away and you'll eventually automatically get revived, but what if this was in Apex legends? Once you get knocked, you crawl to a somewhat safe space, then hold action/ reload to turn into a void version of yourself. You can either pick up some loot and help your squad revive yourself or just go and revive yourself.

Should this be a legend passive? Legend perk upgrade, Legendary knockdown shield perk, survival item, Ultimate that applies to your whole squad. Or even just straight up just give us the Who's who perk machine?😄
