It also looks like you could tap the right side of the return just behind the grille to penatrate the bedroom wall, adding a return to each bedroom is recommended

I'm not sure why I never responded to this (I probably didn't understand the suggestion then), but to the right of this plenum is concrete and earth. To the left is the basement room that houses the furnace, air handler, evaporator, and hot water heater. There are no easy options to increase the grill area for the return here, and besides all that I have a hunch the 12" return plenum to the upstairs is undersized. Considering the same square footage upstairs vs down, shouldn't the returns be matched? The only reason I can think to have an unbalanced return is to send more of the heated upstairs air downstairs during the winter.
I had one kid right out of high school come out and look at my situation, and he essentially said he could do anything, which is unhelpful. I'll look around and see if anyone has ideas that pass my basic logic filters.
What drives me insane is that I'm relying on "experts" to solve problems that "experts" created in the first place. What kind of moron who only builds roofs engineers 800 sq/in of attic exhaust, and and 58sq/in of intake? What kind of moron who only installs HVAC doesn't install adequate return, or even seal it to anything, or even align it with the return grill?
Now I need to reach out to these pool of deplorables for their "expert" remedy.
Everyone should feel ashamed of themselves. No inspector should have given a passing mark for anything. I have utter contempt for everything.
