What about moving up the rotary switches to align with the pots on either side and locating the CV Invert toggle switches right below the rotaries, also between and aligned with two pots? All jacks at the bottom. There would be space for a second CV input for each filter. This would be a variant of the horizontal design, placing all the controls for each filter together, but isolating the jacks at the bottom, MOTM-style.

Well, the way I see it we need at minimum, for each filter, four pots, a rotary or something like that, and three jacks.

Four-position slide? It's defo non-MOTM standard...

Definitely no moving jacks above pots! Very important part of the MOTM layout style.

What if the Mode switch were a 4-position slide switch? Would it fit beside the CV Invert switch to make a 2U layout? I see from the schematic that it's only single pole, and SP4T slide switches are readily available. For instance Digi-Key has this one for $2:

If it wouldn't fit, could we replace the CV Invert switch by a switch on the Frequency CV pot, to make more room for the Mode slide switch? Maybe a switched pot is a little easier to find than concentric ones? For instance Digi-Key has this 100K linear carbon switched pot for $3.50:

I'd really like a 2U layout.

Yeah, I always balk at moving jack above pots, though that's a little silly. If you have more than one row of modules, you're going to get cords over your pots anyway, right?

What do others feel about this?

I really wanted to do 2U, but I don't think folks (and I count myself as one of these folks) have access to concentric pots.

Wow, tough call! If I were doing it for myself, I would do one of two things. If I went with the horizontal version I’d go off the standard MOTM grid and move filter A’s jacks up into the section with the controls and move section B down a bit etc. But if I really was going to build this I would do the vertical design but in 2U instead of 3U by combining the Frequency and Frequency CV controls into a dual concentric pot (if possible), moving the Mode switches down to where the Frequency CV controls were and then move the Input jacks up and the Output jacks over underneath the Input jacks.
