I've owned ebjds for several years, and am involved with the two boards that specialize in jds and ebjds. While SOME ebjds can hang with regular jds, MOST cannot. Breeding ebjds requires a regular jd, and breeding is almost always a male ebjd with a (smaller) female jd precisely BECAUSE they tend not to be as hearty and get the stuffing kicked out of them. In my experience in owning about 15 of these over the years, I view them as community fish, not as an aggressive species (as jds are usually classified).
So... I would be concerned about regular jds being in the tank with the ebjds. The sal might also chase them around and make them hide all the time. My (smaller) female did exactly that; had all three of my larger ebjds hiding in a corner of my 75g, and I had to take her out (to be fair, she really doesn't play nicely with others

). Would be a great color combo if you could get away with it, though.
If it were me, I'd be looking at multispinosas (especially the orange morphs), maybe sevs (but they get kind of big), firemouth (if they're small enough that their bullying instincts are kept in check). You could get away with Honduran Red Points (or other cryptoheros), but they're blue also, so that could be a little too much "blue" for one tank. The orange rainbows and the blue ebjds would be a nice mix, imo.
