The egg crate is probably the best option. I'm not sure having a breeding group of aggressive fish in 2ft of tank will work for a long period though.
Unless this is short term, 24x18 for adults of those species just seems way wrong to me.

Maybe It's just my hongi then haha.I believe you but just want to point out that a 29G is 30" long and half a 75G is 24" long.
IME I have had problems even breeding stuartgranti peacocks (let alone an aggressive mbuna like hongi) in a 36" tank so we have had different experiences.
I had many breeding setups with different species in 29's and all of them were happy and breeding(I also put in extra hiding spaces).The 29 gallon is 30''x12'' and that makes it have the footprint of 360 square inches. Half of a 75 gallon is 24''x18'' which has a footprint of 432 square inches. So if I were to breed the two in this tank it would be better than having one group in a 29.Unless this is short term, 24x18 for adults of those species just seems way wrong to me.

Agree, I always use egg crate (AKA light diffuser in some hardware stores), it allows for almost completely unrestricted water flow for filtration, yet keeps adult cichlids apart. When I cut it to fit, I use the trimmings to brace horizontal pieces with vertical ones, below, and on the sides, using zip ties to secure them together
Also like to cut a notch to securely fit the divider into the aquariums frame.
I sometimes place rocks on horizontal pieces to add more security.
