You mentioned Grisman, which reminded me of Old and In The Way and his associate in that band, Vassar Clements, who was clearly not a Jazz musician but nevertheless quite "jazzy" in his approach. I’m guessing he was influenced in this regard by way of Western Swing. I’ve always liked his playing.
On a completely different tangent, I once saw Yehudi Menuhin with Ravi Shankar and a band composed of L. A. studio players including Bud Shank and Dennis Budimir play outdoors in Ojai. It was supposed to be some sort of Indo-Jazz Fusion but I don’t remember the music, as this was back in the 70’s. You can interpret that as you will ... ;o)
You’ve got me curious. Which heavenly bodies do you associate with other well-known trumpet players?
