Sounds like good organizational planning! Love that you are helping to preserve Buckeyes! With a big run or free ranging chickens only use coops for laying or roosting so they don't need to be huge. We got a tall coop only cuz we have hot hot hot SoCalif weather & heat rises in tall coops.
We looked into Omelet cubes decade ago cuz of easy maintenance but their styles, sizes, wire runs, & accessories were flimsy IMO for the cost. Now they've listened to customer complaints & made some great improvements yet still not the kind we needed. But as w/ any pre-fab coop, they will never be 100% perfect.
We wanted our run to be sturdy kennel wire, have a coop much higher off the ground w/ a tall roof w/wall vents for heat escape, windows, & actual perches rather than the plastic perch floor the Omelet has. I loved so much about the Omelet except for the features we particularly needed. & as w/ any pre-fab coop, the mfrs always claim it holds more chickens than it should!!! That gripes my goat about ANY pre-fab mfr... but I digress...
Anyway, our old Chicken Condos Barn Coop met just about every need we had 11 yrs ago & still does today for the same equivalent cost of the premium Omelet at that time. Our coop's mfr came out w/ a plastic barn design in the same size yrs later & that is the only part I wish was available 11 yrs ago but not enough of an improvement to switch out our current Barn Coop which still has better features for us than their newest barn model.

Our old customized 4'x4' Chicken Condo Barn Coop came w/ solid floor tray for winter, kennel wire floor for summer, 2 windows, 5 variable height perch slots, cleated ramp, large air vents both ends, dog kennel wire run, tractor wheels ~ we keep it on a slab patio w/ patio roof overhead. Perfect for our half dozen birds but certainly not for the mfr's recommended 15-20 birds!!! (Never believe a mfr's recommended capacity when buying pre-fab!)
