David,
EXCELLENT writeup. Can I suggest one correction and a couple additions?
I don't think Louis Johnson ever did anything with Rose Royce. I'm fairly certain it was Lequient Jobe playing the Series I with that group. I could be wrong, but that's how I remember it. Louis did play a lot on Quincy Jones albums and for artists Quincy produced, like Michael Jacksons' first two big solo albums (Off The Wall, Thriller) but I don't know if he played an Alembic on any of those.
You could consider noting Prince bassist Brown Mark played a Spoiler on several hits recorded by the Purple One. You might also consider adding that Flea of the Red Hot Chili Peppers played an Alembic Epic on many of the tracks recorded for the One Hot Minute collection.
Peace,
James
