With a suitable pedalboard that should be very doable, and yes, the less ”circuit” you have in the guitar the more output you will get. However, the tone might not be what you want. Pickups are usually voiced for guitars with a volume and a tone (which affect the sound), so removing them might make the pickup sound bad. I asked the manufacturer when I made my guitar, and that pickup (Pariah Pasadena White) has been voiced in a guitar that only has a a volume, so I planned the ”circuit” around it, accordingly.
