Raingler specifically designed a divider that suits your description of need!
It even has a small pass-thru opening that velcros that enables to grab something from the back (like a sandwich from a cooler on a roadtrip)...
Two hooks on the net that grab onto the built-in tie downs. I have the OEM rubber cargo floor cover, so I simply cut slits to allow the tie-downs to protrude.
2 door cargo covers just got designed by Raingler Nets and Barriers!

Raingler Nets and Barriers offers 2 door Bronco owners a solution to cover/contain our cargo with our hard tops removed. No drilling or modification required.
I offered up my 2 dr WildTrak to Raingler for product prototype and fit checks.
They made a cargo net that attaches at the hardtop...
Home Depot has diamond-zee patterned foam rubber mat material on small rolls. That is a nice cushy addition on top of the lay-flat platform. Helps the knees when crawling in/out.
I am taking my 2 Dr over to Raingler this Thursday to help him with measurements for his 2 dr Bronco products.
I will definitely be encouraging him to make a cargo/tonneau cover that can quickly attach/detach from the hard top bolt hole locations. I have the Rockworkx thumbscrews, so...
Thank you for the great response!
I am headed to AZ in March for a couple of months. Was hoping to get them installed on the way down from WA. With a full cargo of suitcases, golf clubs, etc.,, there's no way I can squeeze them into my 2 dr cargo area.
