Mine would need to have a unique shape (interesting that everyone so far seems to go for existing bodies). Probably something like an offset waist Tele body.

Something like that body shape but without the overly exaggerated top bout, and with an actual offset waist.

Or like that, but with squarer corners - not so rounded and LP-ish.
Black scratchplate. As for the finish: maybe natural, maybe seafoam green.
Bareknuckle Abraxas bridge, Trilogy neck.
Arcade button killswitch, situated more or less halfway between the pickups, near the tone/volume controls.
One master volume, one master no-load tone. Three-way toggle for pickup selection and a coil split toggle for the Abraxas.
Hardtail with Graph Tech saddles. Graph Tech nut. Schaller locking tuners. Schaller strap locks.
...yeah I think that's about it.
