Unfortunately the typical church organ in this country has been the living room jazz organ. Anyway, what I had in mind was adapting 3-staff keyboard scores for the piano and bass. Adding drums to a standard Lutheran chorale at the organ spells musical disaster. Again you have complementary instruments, not congruent ones. A modern drum kit is infinitely more versatile than a few jumbos.
Good players know what to do.
Others can be taught. Regarding the bass guitarist, the only opportunity I missed was one of musical incongruity. A bit more was missed here, I think. Geniuses like Vivaldi and Hovhaness have paired unusual instruments for centuries. I have a recording that includes a piano-electric bass duet of a Debussy prelude.
