Bocete-
very cool idea- reminds me of a story.
Many moons ago -when Sheldon released the Afterburner basses- a few of us adventurous folks asked for special things (like custom tone woods, custom tops, BEAD setups, different p'up configuration, etc) and sheldon was kinda accommodating for a very short while (made a totally cool BEAD bass for Basscentral)- til i guess he figured out that he didnt want to make a "less expensive" versions of Z1 or Z2 using the ABI as the backdrop.
I even asked him for a Z2 configured Ash bodied ABI back in the day(02), and besides his comments about Z2 p'up configurations are not doable on ABI as the neck pockets are too different, he thought about possibilities, and I guess came to final conclusion for this venture to work- it had to be cost effective, and anything that deviated away from the standard production- was not cost effective.
So I really dig your mockup- but unless Sheldon gets boinked on the head
my guess will be you can get black hardware -maybe
