I don't understand Miles in this list of the pantheon of most influential. Miles is sui generis as you put it for Duke. What trumpeters after Miles sound like Miles? Maybe I'm missing someone but they all seem to come from Dizzy/Clifford or Freddie Hubbard.
I think Bud and Clifford have to be on the list of most influential.
Yes, I've put Bud and Clifford. As for Miles, think of his legacy in weakening the hold of bop with his Coltrane, Garland, Chambers, Philly quintet, the continuing influence up to today of his Shorter, Hancock, Williams quintet and the impact of his "electric" period. Ellington, too, was hugely influential on just about everyone who wrote and arranged jazz after him, Mingus incuded, who I don't think should be on the list BTW. Didn't Miles say somehting like "All the cats should get down on their knees and thank Duke"?
