I stopped trying to swap pickups to match a sound in my head, instead I like to experiment with the tone/volume controls to find that sound I'm looking for.
Being a semi-hollow body user with Seth Lovers, I find those pickups to be my perfect combination. Usually the Seth Lover neck position will be a bit more on the darker/woodier/muddier tone, which when paired on high-gain amps, can be absolutely marvelous, sort of a Slash tone. If you play Jazz, roll back the tone knob on the same neck pickup and you're in prime jazz tone area.
Instead of messing with pickup swap, my favorite position is the middle. I roll the volume down on the neck pickup and the sound is fabulous. I get a little bite from the bridge and a tad bit of warmth from the neck. When I'm ready for a more bite in the solo, I jump down to the bridge. If the middle position is too mellow, decrease the neck volume a small amount, if it is too bright, increase the neck volume.
I get what you're trying to do, but I'd try that first. So often, we jump from Neck to Middle, but forget there is a middle position. Using that middle and the adjusting of tone controls, you just might find your happy place....
