with a push pull volume with the correct resistance and a push pull volume of the correct resistance, you'll be able to get it done.
for humbuckers, volume impedance should be from 500k to 1meg depending on your feeling (the higher impedance, the brighter you get)
for tone... i guess it varies. some like 250k for hums. some like 500k. some like 1meg
default manufacturer value will be around 500k for volume and 500k for tone
gibson is known to use 330k for volume and tone
if you want to split both pickups at the same time, only a single push pull will be needed. but for independent control, you need two PP's
if you have any other questions. ask away :D
