This sounds good to me. So 7 knobs, 1 switch, 8 jacks, right? A typical full 2U panel. Do you need a mockup? What do you want the labels to say? Your thinking behind making OUT2 the 6x1 output is that with only 1 output jack inserted, the main out is at the corner of the module? Either OUT1 or OUT2 as the 6x1 output works for me. I agree with Larry that whichever output works as the 6x1, that's the one that the offset pot must be summed with, so that it can work at all times.
