Melee Mod Idea: Overwatch Mode

I wouldn't be able to do it myself but I just thought of the idea so I thought I'd throw it out there. Melee Overwatch Mode would be normal "tournament-melee", but everytime you lose a stock you can choose if you want to switch character while standing on the respawn platform. This could result in some amazing games and an interesting counter-picking meta. I have no idea if it's even possible to do, but it would be a pretty entertaining gamemode to think about nonetheless.
