Yep. Or look at Marawuffs' Palmer armor. I liked what she did there too.
If you can live with silver instead of white, cutting out the needed shape out of a cheap silver tinted motorcycle visor, and match the color of the helmet markings accordingly. That would give you the easiest option to match visor and markings in a manner that allows you to integrate the visor ports as invisable as possible while maintaining the best possible visability for the wearer.
