311H Pickup Compatability With Other Pacificas?

I have a 311H which I love. It comes standard with a humbucker at the bridge and a P90 at the neck.

These sound pretty good to my ear, but, (you knew there was a 'but' coming huh ;-) I find I rarely use the humbucker by itself and mostly have the toggle set to the P90 or to both pickups with the tone knob pulled up to split the humbucker (which doesn't seem all that 'splittable').

Also, while the difference in the various setting options is noticeable, it is pretty subtle to my untrained ear and I'd prefer to have pickups with a bit more pronounced difference in sound.

Wondering if it's possible to replace these pickups with those from "higher end" Pacificas like maybe the 611, which (I think) has a Seymour Duncan SP90-1N at the neck and a Seymour Duncan TB-14 at the bridge.

Goal would be have these (or others if you have suggestions) as a good 'drop in / no mods necessary' option and to use the same wiring and switchgear but improve the sound and the difference between settings.

Any suggestions/concerns/crys of outrage and dismay ? ;-)

TIA!
