Love the sound of a Mudbucker. Love the sound of a Stingray. Combining the two might be too much of a good thing or it might be pure bliss. I have a test mule and a spare stingray pickup and preamps, I’d just need to buy a vintage Mudbucker to see how the combo sounds. I know the Mudbucker can be pretty overpowering so it would be interesting to find out how well it blends with the Ray pup, an active preamp would be essential for the loading or possibly a dedicated volume and bass treble stack for each pickup. Years ago I worked with John East to build a similar custom preamp for a stingray/P bass build I did. It came out great.
