No , I think your Zappa analogy doesn't play here.
Parallels between Kamasi and Sun Ra:
1.Two large scale orchestras + singers & dancers, playing non-conventional music.
2.Both play original tunes, no standards.
3.Both woodshed-ed, and pretty much lived together with other band members [according to the NYT piece on KW that's what he did/does].
4.Both would draw large non-jazz audiences. For example, I heard Sun Ra on the same bill with the Sonic Youth.
Those are just the obvious similarities.
