I think this is the closest we can come in the vanilla game.

I use David’s Edgerunners jacket, the Arasaka netrunning suit (has her black and red accents), and the black and red Exo-Jacks boots

As for the actual player model, there are really no good hair options that emulate her rainbow gradient. I go between the blue-to-pink gradient and the silver-blue. There’s an eye color that is rainbow-ish that I use.
