⬅️ Old coop worked okay for five years...but new and improved...so far, not so much.

I know you are hoping for some "hands on" help - but failing that you could take and post some photos and provide the reasons the new coop isn't working for you and we can help you troubleshoot from here. There are lots of members here who are quite experienced in coop design, re-design and troubleshooting.
The bars are too close to one another (do you have so many chickens that you need all 3 bars?) so I would take out at least one if possible. You didn't specify how many chickens you have nor how long each roost is.
Headspace is a big issue. The coop shape was designed to look cute with no thought of the fact that chickens need head room to be able to get up onto the roost bars. 8" definitely isn't enough. Ideally you'd want to drop down the roosts, so you can try putting in a vertical beam (or beams, depending on how many roosts you need) from where the roost brackets are now, straight down towards the floor. Secure them top and bottom. Run new roost bars horizontally across and secure at the ends to the new vertical supports. This will eat up all the floor space inside the top unit though, so other than roosting and nest boxes, the upper part of the enclosure won't really be usable at all.
Well an alternative to my suggestion would be to run vertical beams from the top, as previously mentioned, but have it very securely attached at top and not on the floor, with the roosts secured between the vertical beams. So you could still slide out the poop trays. You can put the roost bars as high or low as you want, and given that you're trying to maximize headspace, you could probably have them fairly low, maybe just a few inches off the "ground" (poop tray).
I wonder if you could raise the whole thing up about 4 feet? Like build a pedestal for this to sit on top of? Make it out of 2x4 and wrap it in hardware cloth, then you could mount roosts under the current floor for them to actually sleep on and use the loft, your current coop, for storage instead of sleeping? You could close off one side with painted plywood or corrugated as a wind block. But otherwise our temps don't get low enough in SoCal where they'll get too cold. Those few nights it gets into the low 40s they could just huddle together.
