I have looked into using the snap on vintage bubble visors to old school open face motorcycle helmets. They are pretty cheap, but only come in clear and smoke tint. They have the signature double curved look of the master cheifs visor (meaning it curves both up to down, and side to side). However they arent gold tinted.
If someone could source up someone whom could do this, or possibly contact a motorcycle helmet MFG'er that makes the iridium coated visors, like HJC, or shoei, we might be able to get a deal on a run of them.
JUst buy translucent wrapping plastic. Like the stuff that brat on willy wonka throws around when she is pmsing. put that behind the non tinted visor and it is magically tinted. Tell me if it works cuz i havent done it personally it just seems like it would be perfect.
