Yes, but Taylor has infinitely more experience with building and the details than any of us. Sometimes customers ask for combinations that just won't work very well. They are trying to protect us from ourselves, and avoid having odd or marginal guitars out there.
I once asked for a baritone neck on a jumbo body, figuring that the larger body volume would support the low frequencies better - I even discussed it personally with Andy Powers at a Road Show and he thought the concept was promising. Later I tested my theory on a 315 that was tuned down. (The 315 clearly had more bass response than the rosewood six string GS / 800 series baritone, kinda like the LKSM tuned down). But they had stopped building jumbos by then and refused to even consider it, even as a BTO. I still think it would work.... but we'll never know. Maybe I should consider converting my 615ce with a new nut and heavy strings...... hmmmm.
