There's no black and white zebra listed
here.
but I'm sure you could ask for one to be made :)
A 500k pot works fine in HSS, you might find that your singles have more high end than usual but its not a bad thing.
EDIT, oops, maybe you meant a zebra HB and cream covers on the singles? yeah, that would be possible. Check out the colour options on the products page, you can mix and match as much as you like when you order.
