Even though the Flagtail is on my 'list for the future' I think it is probably the odd one out in the group; being very active and rather skittish, whereas all of the others (except maybe the cats at times) are generally quite graceful and fairly slow moving. Therefore I think if you dropped it from the stocking, the setup could potentially work quite well,
I wouldn't be too worried about the EBJD if you can find one that is around 5-6" which would generally turn out to be quite a strong/healthy specimen if it has survived to that size, that said it may turn out to be the most expensive purchase,
To get an idea of the size of the tank and how the fish would look in this kind of setup it may be worth searching through youtube, IMO 5 medium to large cichlids and then 4 others (which potentially will be hidden much of the time) would be fine in a tank of this size.
This vid shows a 200G tank, not the same dimensions granted but a similar number of species)
