Hi mods! Riffing off the support character idea, would it be possible to introduce another role, which could be characters opting into taking a defensive/rescuer role?

The way we envision it could work is that if an offensive character gets a bad roll to the extent they're at risk of severe injury/dissipation, a defensive character could step in to tank the hit for them or get them to safety, giving the attacker an opportunity to keep fighting. It would be another way that characters could contribute who don't have much offensive capability, but who might be tough/fast/...unlucky... enough to help a stronger member of the team. (This would be a one time only thing, so the defensive character would only have one chance to contribute, to be clear.)
