series/split/parallel but with a DPDT on/on switch and a pot...?

[Danage]

In my head, there is no reason why this shouldn't work, but I thought it'd be a good idea to check with people who probably know better... 

let's consider the following humbucker wiring:
Coil A negative > Ground
Coil A positive > volume pot > series/parallel switch > master volume
Coil B negative > series/parallel switch > master volume
Coil B positive > series/parallel switch > master volume

Now, in my head, with the volume pot all the way off, you'd have a single coil sound, regard less of where the switch is. But then you could blend in the second coil in either series or parallel. 

So you'd get everything that you'd have from a series/split/parallel set up, but even more with the blend... and it could all be done on a single push-pull pot..?
