The shape is not so complex that it can not be approximated by conventional means using off the shelf items. Game accurate would be Dark Blue refelctive visors, and I can not get that from a vac formed visor. So, for now, No.
Its as big as my Legendary Armor Helmet, yes its a bit larger than My MK VI to accommodate those big head folks.... About on par size wise with Docs MK VI...
Photo shopped in the paint scheme over my helmet, thought I'd share what it may look like... greys on blacks... per H3
