I wouldn't mind a spectator mode. I think that the best way to do it during a match would be to make it a weapon like the recon droid in Star Wars Battlefront II. Maybe make it a secondary and more as a scouting weapon with really low damage numbers, like ARC, when it's cold low. Maybe you could even add a self destruct feature that acts like a grenade. I guess you could even make it a grenade. No real direction here, just throwing out some ideas (though your idea sounds fun in my opinion).
