Congo biotope advise needed

Hi all, i have made a change of direction after ten years, from ca cichlids to W African tank. I plan to do a congo biotope in my large 8 foot by 3 foot tank.
I've acquired congo tetras and some barbus sp, as dithers. I have some juvenile H Lillafili.
Please could you advise how many and what kind of dwarf or smaller biotope correct cichlids I could achieve safely in such a set up? I understand some feel the Jewel wont work. Am interested in blockheads, kribs, nanchromis, lamps, and mouthbrooders. Plus a possible mini cat.
Thanks
