I agree that folks should try / experiment with whatever they feel helps them the most.
Years ago, I tried reversing the standard Stick tuning and put ascending 5ths on my melody side and ascending 4ths on the bass. My reasoning was that having the bass side in fourths would help me as I started out as a bass player and I had also gone on a GuitarCraft seminar at one point, so I like the Crafty tuning of guitar in 5ths. Flipping each side kept the same general relationship of hand motion just as regular Stick tuning does.
However, I eventually came back to normal tuning for all the reasons that went into Emmett's original concept: bass in 4ths leads to closer voiced chords which sound muddy and unclear and close voiced chords in melody 5ths were harder to achieve so you sort of ended up having fewer choices on the melody side. So, thru my experimentation, the original wisdom of the instrument was revealed to me.....
I guess that Chapman guy knew what he was doing....
