I'd get Delhezi or Senegal. Well and I like your rope idea of course but I think you're saying the ropes will go in the larger tank to start? Or no?
I think the Buettekoferi are reported to generally be shy so not sure it'd be the best bet to go with potentially aggressive cichlids. I'd go with a more outgoing species for that. If they had Polli on the list I'd recommend one of those for sure. Palmas would probably work, and they have TR ones. I feel like WC fish are more likely to be shy than TR as a general rule...
Excited for you to get going!!
