The clone of SRV is Kenny Wayne Shepared. If you want a jazzy instrumental jazz/blues sound like in Riviera Paradise, Ronnie Earl and the Broadcasters, he is the man. He is more jazz/blues like Rivera than versus the other SRV more blues/rock sound (for lack of a better definition) which is one of my all time favorite songs too. Rivera uses more cording on the guitar to create the song where Ronnie's playing is more playing along with the song and some cord based melody. The other guitarists you mention and that others have mentioned do not sound like Rivera at all. I can burn you a copy of a few CDs if you want, just email me.
Happy Listening.
