Avoiding fish that closely resemble one another is the most important thing about an all-male set up. There's a few here and there that have some resemblance, but in such a large tank, I don't foresee any real problems.
I think the biggest problem you're going to have is finding some of the fish on your list. Some of them just aren't readily available or available at all.
Placidochromis sp. "blue otter" - I've searched for these for years... never found one.
Protomelas spilonotus (Likoma) - same as above.
Lethrinops sp. "mbasi creek" - very uncommon.
I'd be very interested to hear if you have a lead on these already or if you find them.
