not sure how to get that to work. but mini-switches are small (hence the name) and can normally be fitted into a control cavity quite discretely with only one extra hole needing to be drilled. I would check to see if you have room for that - if you dont i would go with a single push/pull for series/parallel operation and forget the single coil option
If the guitar has volume and tone there is normally enough room between them to fit a mini-switch
