I dont know is this will help you. I use the jazz flats on my 5 string P. The TI has a more define B string than the La Bella LTF 5 string set that I used prior
Aero pickups did it for me and 1 have a 34 scale 5 String P. It's a transparent pickup like a single P. With height pickup you can obtain los of sounds.

Bill Lawrence P-46. It was design for basses of 4, 5 and 6 strings, and sounds really cool for its price range.

I had it in the plucking hand. The doctor said there where 2 options. Dont bend your wrist or stop playing bass.
The way that Gary Willis and Pino Palladino have their plucking hand helped me a lot.
