Complex A/B and loop box

[seten]

I'm soooo close to making this work but I'm not sure if its possible. I'm trying to build a box with four switches, three 3pdt and one 4pdt. One is wired as a bypass for an effects loop, one is a bypass for an A/B send/return system, and the last one is for switching between A and B. All thats simple enough but then I wanted a 4pdt for switching between having the effects loop before or after the A/B system.

Two questions: 1 is this possible with a 4pdt or will I have to go up to a 5pdt or even 6pdt (not sure where the hell I'd find those) and 2 if there are two paths for your signal to take, one of them going straight to the final out of the box and the other going through the pedals in the effects loop or the A/B loop,  will it take one or both? I'm guessing it will mostly or entirely just go straight out of the box since that must have less resistance than going through whatever guitar pedal i have in the effect loop.

UPDATE: Figured it out! Would still like to know the answer to question two though, and also I have an issue. I plan to place two high gain pedals in the A/B switch so I figure itll be a good idea to ground the output on that when the whole A/B circuit is bypassed. Originally I thought to connect pin 5 of "A/B" to pin 8 of "A/B Bypass", but then I realized that would also ground everything that pin 5 is connected to, not just Return A or B. Any ideas? Should I even be too concerned with this?

Building this tomorrow so bumpin it back to the top to see if anyone has any ideas for grounding the output of the selected side of A/B when the whole A/B system is bypassed.
