Let's say John,Jeff, Jay and Oteil are going forward. Who do want to be the second guitar player and percussionist?

My obvious choice for guitar is Scotty Metzger of JRAD. He has long been the choice for second guitar for many other artists, knows the catalog and can also solo with the best of them. For percussion I think Jim Loughlin of moe. Would be incredible. I mean throw a marimba in the mix? If not him Nate Werth of Snarky Puppy/Ghost-Note.
