Variatone-like Switch

[Fernando Esteves]

Hello!
I'm building a guitar with a single humbucker in the bridge.
For a lot of reasons, I decided to not put a humbucker in the neck, but I want to use a 2-way switch to warm a little bit the bridge tone, something alike a Variatone switch, but a bit on middle and treble frequencies...

Problem is: I'm a completely loser on electric wiring...
Anybody does have an idea on capacitor values to have this effect and how to wire it?

Thanks a lot

EDIT - One of the reasons I don't want to put a neck pickup is that I don't really like neck pickups.
My idea is something in between a bridge and neck, a bit warmer and less bitey, but not exactly like a neck humbucker
