If you can afford 3D printing, you can look to print sets of them (if you have a 3D model or ask someone to create them). In Shapeways Frosted you could get the "transparency" the original missed.
Or you could use Puppetswar mechanical wings and do a "cyborg" themed vespid nest (a way for the crippled to serve: wings are semi-autonomous drones that interface with the vespid until death and return on their own after to the garage).https://puppetswar.eu/product.php?id_product=234
Onos have done on our board (can't find the thread) some insectoid wings from transparent plastic sheets engraved with patterns.
Or you can cast them from an original (parts could be press molded easily with Instamold and Greenstuff).
Lastly, you can pray GW to release plastic vespids...
