Andrew, your 2U Doomsday Machine panel is chock full! You've taken the 
idea of panel density to the max. Jacks can certainly be closer 
together than MOTM. A 7/8-inch vertical jack spacing makes for a square 
jacks grid like Modcan B. What type of pots did you use? Those look 
like Blacet knobs.

I tested with knobs taken off the Encore UEG, which uses a 7/8-inch 
vertical spacing between pots. The pot grid on the experimental panels 
is 1-inch vertical spacing and 7/8-inch horizontal, the same as the 
standard MOTM jack spacing. The knobs fit fine and there is enough 
vertical clearance between them to place a standard label. I put the 
labels above the pots and placed the top row as close as possible to the 
top of the panel while leaving room for the pot behind and the label in 
front. I am not sure if there is room for eight 1-inch spaced positions 
bottom to top; the top pot seems to come too close and there isn't much 
room for a label above. Labels could be moved below. I'm going to 
experiment more by making a mock panel of cardboard and checking the fit.

And you are making me re-think the idea of a 7/8-inch square grid all 
the way! But there is still the advantage with 1-inch vertical spacing 
that a Bridechamber 3-jack bracket can be used. In fact, this is what I 
think will work to mount the CGS Super Psycho Modulation Source PC board.

And that begs the question: How did you mount PC boards to your 
Doomsday Machine panel?
