What would be an appropriate recolouring? I imagine technical limitations will be the major decision maker there, but being ignorant of what those might look like I’d vote for black, with hints of green, effectively applying the colour scheme of the Death Trooper armour from Rogue One to Phasma’s armour. Looks like we’re not going to see black troopers in the sequel trilogy, so it’d make this new trooper distinct as a clearly important trooper while still being consistent with other imperial schemes.
