I guess it would depend on how large the screen is, is it curved, and if you can get the camera FOV to line-up with the visor FOV.
So yeah,
theoretically this is possible. However I would have no idea if the OLED screen would work in practice. It might be of some help to get some orthographic sketches of the layout made, and show some photos and names of the products you'd use.
Also concerned with how much a translucent OLED screen would cost, and the implementation into the helmet. I'd assume it'd be more suited for a Halo CE Marine type of use, like so.

I'm a real lover for insane, bold projects. But I can't feasibly see this happening in practicality. Ready to be proved wrong tho!
