Consider before you do that, if each pickup has its own volume and tone, the 2 and 4 positions will be seeing 4 pots, which will sound hella dark, so you'd want to use 500k pots. Also, your controls will be extremely interactive, no matter how you slice it. You'd need to put a treble bleed on every volume control if you didn't want the whole thing to turn into a muddy mess. Plus you're volume controls would be coupled, so turning off the middle pickup for example would turn also mute the 2 and 4 positions.
Also consider, how often do you feel that you need to change the volume of one pickup relative to the others? This wiring configuration is a whole lot of trouble and you get no more useful sounds than a normal strat has.
