2 effects, 1 pedal box, with order switcher and bi-colour LED

[navin]

So I have built 2 overdrives and now I want to put them in a single box and have a common b-color LED to show which is operation.

The Options I want are:

Drive 1                 - blue LED
Drive 2                - red LED
Drive 1-> Drive 2 - purple (blue + red) LED
Drive 2-> Drive 1- purple (blue + red) LED

Can I do this using just 3 3PDTs?

Anyone have a schematic for this? I tried googleing but could not find any.
