More details have come to light thanks to Rick Turner, the guitar maker who created Lindsey's signature electric guitar - he shared this on Facebook but gave permission for them to be reposted:
According to Rick Turner:"At one point, Lindsey had proposed that both FM and he with his band tour at the same time with the LB band filling in dates between the FM shows. The report was that Stevie wanted at least a day between gigs; Lindsey wanted to play as much as possible. That's what I heard from a most reliable source at the NAMM show in January.

I think it just points out one point of contention. Maybe it looked to some as though LB was going to do really well touring hard; perhaps not doubling his money on the tour, but certainly getting in nearly twice the audience face time. I did not hear whether Christine was going to possibly do the LB gigs as well as the FM gigs, but Bret [Tuggle, keyboardist] and Neil [Heywood, backing guitarist] would have, and that would have made nice...and deserved...paydays for them. Good guys, great musicians. I know Federico [Pol, Lindsey's bass player] was looking forward to it, too.

Lindsey would have gotten more press than Stevie if they'd done a double tour like that.

Well, it would just be two interlaced tours with some of the folks working practically every night [in different cities]. But that's what they do in musical theater...Broadway and off-Broadway actors do eight shows a week...six nights and two matinees. That's what professionals are capable of. At one point the Beach Boys were often enough doing two gigs on the same day, and on at least one day, they did three...in three different cities. Lot's of alimony to pay for those guys!

It would have been doable. It just needed everyone's buy-in."
