Rob,
well you are the CAD master. Great work!!!
I already spoke to Mica rgdg this project so you see that this is really used. I need this beast... :-)
As with the 8er peghead this will not work I think. What about having the normal DW peghead made a big longer and have the tunners arrayed like on Johns Status Buzzard with 6 tuners on the left and two on the right? What do you think?

Maybe 3 high and 5 low?

o = Guitar tuner
O = Bass tuner

Rob,
I would rather suggest not to have the lower peghead mirrored.
What do you think of this arrangement, see pic below

Like this:
 

 
Only 1.5 (38.1 mm) longer.

Rob,
if we would use this we need to place 4 on the left side as it will not work with the string spacing. But I would like to see the peghead in a normal position as well to decide what would look better.
Could you do this?
 
Oliver (Spyderman)

I do'nt see why it won't work with the string spacing...?
 

 
I think the reverse version looks much meaner (in combination with the other neck)

Two variations. Maybe it will look better with the pegheads the same way...
 

Rob, personally (my taste) I would prefer the two pegheads in line, classic layout. This looks more smooth to me. What do you think? Could you put a vermillion veneer on the tops of the headstock?  

 As for the tailpiece I like the double version you showed on the original photo. Electronicwise I would go for the same 20th Anniversary than in my actual DW and only for one set of electronics  due to lack of space, means knob layout as on my DW and with an additional selector switch for the two necks, maybe located centered in the space behind the two bridge pickups?

 Oliver (Spyderman)

Ok.
Do You know where I can get some drawings/blueprints of the knobs and the selector switches?
 
Isn't the area behind the bridges and in front of the tailpiece better for a switch?

Rob,
yep that would be a great place, better I think.
As for drawings I must pass; if I remember there are some pictures on the Alembic store? Would this help too?
Will take a look....
 
Oliver (Spyderman)

Rob, only these photos

Must be somewere it can be found.... who is the manufacturer?
I don't think Alembic makes those things themselves.

Found one of them .... now... size?

Rob,
the pointer knob has a height of 1,2cms, a lenght from round end to point of 1,8cms and a diameter where the round part goes into the angle of 1,2cms.
The round knobs are 2,15cms height in total, 1,9 without the lower rim, diameter is 2,5cms at base and at top it has 1,5cms.

Thanks. That should do it, or, close enough.
