Michael,
Give this a look: www.lempertgroup.com
He makes wheels per order, to your specs. I needed a 120 degree 3 spoke Derrington style in 14" on Moto Lita hub a couple of years ago. No problem. And, reasonable $$! (actually I think that is mine pictured in the Signature Series, mahogony Derrington).
If he is still at it, tell him what you want and prepare to be pleased. Pretty quick too!
