Hi John!
Basically, why not, but I dunno whether there is enough interest to make it worthwile? Not in the sense of making a huge profit, but at least covering expenses.
IIRC Trev(inoz) has mentioned a friend who had them cast, maybe worth a try?
The railway workshops in Newcastle were responsible for a large number of these appearing on a lot of "sudeo-rockets"
We actually had a member who made up a "suedo-rocket" decal for his rocket styled A10
