BASIC CONCEPT: There now exists a constellation of tunings which share high relatedness. Circular (thanks, Mike Photis!), Major Cross (thanks, Tony Eyers!) and several of Brendan Power's tunings (thanks, BP!) are strikingly similar in structure. This is one such variation, and is particularly similar to PowerChromatic tuning.
WHEN/HOW: July of 2017. Configured by me and constructed by Seydel's Custom Shop.
LAYOUT:

I Gmaj yes
ii Amin yes (x2), with 7ths
iii Bmin yes (x2), with 7ths
IV Cmaj yes (x2), one with 7th
V Dmaj yes (x3), one with 7th
vi Emin yes (full with 7th, and partial)
vii F#dim yes, with 7th
DETAILS: This is four reeds different from PowerChromatic. It is also nearly circular tuning, and nearly Major Cross. Compared to the latter, my layout contains a "point insertion mutation" resulting in a "phase shifting" of the upper tones from blow-to-draw and vice versa. This phase-shift flips the higher octave into a repeating and (in my view) a “proper” blow-draw pattern.
So far, this is my favorite basic diatonic melody/harmony tuning that is not particularly optimized for blues or some other special purpose.
