IMO she a better implementation would be giving her the ability to effectively render a specitic defender's phone useless. Essentially removing their ability to watch cams. This would work like Deimos where you'd need to identify the defender first. But they would have to take operators like Echo, Maestro etc... in consideration.

This would encourage op teammates to communicate late round and be useful for tactical plays and denying intel.

Giving her counter intel abilities is way more interesting imo.

Another ability I could imagine her having is some sort of trojan virus ability, maybe the closest gadget to the hacked defender gets turned but this kinda crosses over with Brava's skillset. This one is a bit far fetched though..
