Nidus Augment for 4th Ability

[(XBOX)UNSC Unit 0257]

I was thinking of a cool augment for nidus and thought about his 4th Ability and how it spawns maggots, however with this augment the maggots could infest two hosts and cause them to deal x% more damage to foes or transform them into infested allies, however in exchange for this it would cut the healing of ravenous in half and cut the duration of the ability by 10%.

I think that if they added another augment for his 4 (no frame has 2 for the same ability), this would be unique enough to fit. Designing this like Revenant’s thralls would make sense, as they are being overwhelmed by Infestation, regardless of their species. You could still attack them, but maybe a confusion-like effect, where they get attacked by others? Turning an enemy into a decoy by overwhelming them would be a different approach for Nidus, a good thing. This would probably have a negative, like 4 costs 7/6/4/3 more mutation stacks to cost.
