No. He did a great job on Burning Bridges and does a good job when playing acoustic shows with JBJ but leave him as a producer. The authenticity angle you mentioned is why I would prefer if Phil recorded guitar leads on the next album. It probably won't happen since Jon says the record is "just about done, I just need to go back in a tweak it". I just hope part of the "tweaking" is adding some guitars by Phil.....
