Need to ask yourself how often do you use a tone control compared to volume control.

On a hot rodded strat copy I had in early 80's I dropped in 3 Bill Lawrence blade PUP's that each had 3 way mini switches and separate volume controls but no tone controls. To be fair it probably had 2 x too many volume controls plus I never was one to tweak away with tone knobs either. If the PUP's are decent quality their unadulterated signal should be good enough.

The HB/P90/S combo will provide plenty of significant tonal differences and if you are not used to soldering and/or doing complex wiring jobs maybe Master Tone & Master Volume with a push/pull coil split for bridge PUP would be the easiest way to go. Definitely what I would do to begin with.
