Malawi peacocks not a good fit, too active, nippy, more aggressive overall, and in a group of them you're likely to get a hyper and very aggressive male or two. If you see profiles saying they're peaceful, this is by comparison to the more aggressive Malawi species, not the more docile among SA species. I know, I bred them for years.
Cyphotilapia (frontosa/gibberosa) no, but altolamps yes? Doesn't make sense, they're from the same lake, and if anything frontosa are less sensitive and more robust than altolamps. I've kept Cyphotilapia for years, occasionally mixed with SAs in secondary tanks, no problem in pH in the mid to upper 7s and temps in the mid 70s to 80. It can be done, but would be more of a front tank with an EBA than a new world tank.
A variety of geo species would work, they do pretty well with reasonably peaceful acara types ime, and geos can be anywhere from @6 to @12 inches, depending on species. Severum(s) would work, again, usually do pretty well with reasonably peaceful acara ime. Severums can vary a bit in size; rotkeils, for example, typically end up 8-9 inches or so, others can be 10 inches or larger, depending on type, individual, etc. Ime mesonauta would work, occasionally I've read of aggressive ones, but not my experience. Large, wild angelfish, I've had nice mixes with wild Peru angels. With some species, like chocolate cichlids, it depends on the individual fish. Some pike cichlid species could work. A number of possibilities, with a moderate limitation imo on larger species at adult sizes in terms of numbers.
As far as the thread title-- Absolute biggest cichlid for the tank itself? People have different philosophies on this and tend to cover a spectrum on the overall question of size of tank per size of fish.
