Random Breath power thought- do you know the Certain Scientific Accelerator? Its main character has this sort of power that lets him redirect vectors of pretty much anything that comes into his AIM field (reality warping field that surrounds his body) and even make them stronger. Since Breath is about movement and directions, would this make this vector ability a breath like power?

That’s very much a Space-related power though, motion may be Breath’s jam, but when it comes to something that specific it just sounds like momentum and spatial shenanigans rather than Breath. You may make it work out though I guess.
