I'd be ok with option 1 or option 2 Sonic whatever makes you feel more comfortable. Obviously I would only be building one for myself and I could provide feedback as the build goes along if I have any suggestions. I reckon you should come up with a design for a slide decal that we can put on the guitar that gives credit to you to go with option 1 or 2 if you go down that path.
In regards to your copyright I hope no one stoops to the level to try and steal it and commercialise it for their own gain.
Happy to wind some pickups for you, I'd just need to have a dicussion with you about magnet choice and how hot you want them. I'm tending to use Alnico 2 magnets for my pickups because I like the sound more than Alnico 5. Although humbuckers it's easy enough to switch. If I wound any pickups for people I'd only charge what it cost me in parts because I'm not a pro obviously.
