Yes, the switches you propose have a lot of sense I guess.
Passive multis doesn't work well for audio signals, so I got it the reason for your first proposition. Anyway, for me they are superuseful, not only for audio (that's mainly the reason I use buffered), for modulation too. Ambient music with a lot of modulation is more fun for me :)
But yes, fair enough switch minimix, xaoc dsp and one vails for bartender and barback, even if probably I'll miss the xaoc dsp, it's the best solution I think.
