Every guitar company has a Custom Shop. Some like GMP and Carvin are only custom shops. If you had a chance to get a guitar custom made, who would make it and what specifications would you want.

I would go with Schecter and get a custom Tempest guitar.

Mahogany Set Neck with Ebony fretboard
22 frets

A Pair of Seymour Duncan Pearly Gates pick-ups, Neck nickel plated, bridge open coil
