With that stock list you have some large fish. Definitely need a 6 foot tank.
In a 6 ft 180 tank, I would aim for a total of 15-20 adult fish. Would start with more and weed out any overly aggressive ones. You want to overstock them.
well as for that being a stock list really is not set in stone just posted some of the species I like. So far not many deals out there for a 180. I did find a 150 gallon for a decent deal.
Also after going to a LFS today they had a 180 with about 50 or so cichlids in there as a display tank had some haps peacocks and mbuna. Would that be practical in the long run as well. some smaller mbuna then a few haps/peacocks?
you could (and should!) do a nice colony of s. multipunctatus in this tank. They are fabulous! They need to be in a group and you'd have lots of room, so I'd say 6 or even more.
the main reason I said to go with a 6 foot tank was you mentioned you really wanted a venustus, which gets very large
Just a few thoughts:
the blue orchid peacock (and it's "sister" the maylandi) will not do well in an all male tank. They need to be in a colony set-up
If going with an all male peacock/hap tank, you should avoid more than one male from one species and avoid males that look similar. It's also wise to avoid the more aggressive peacocks, including those with unknown temperaments, such as the dragon blood and OBs.
you can add some of the milder mbuna to an all male peacock/hap tank. You do not need to worry about gender ratios for them, generally speaking. P. acei, rusties and labs are the "go to" species for this type of tank.

Be careful of adding a BN to this set-up. They can sometimes get abused, depending on how laid back your tank is.
Also, with all male tanks, you're likely to get bullies and fish that need to be pulled. (less likely, perhaps, in a larger tank, especially if well rocked). But you'll need a second QT/hospital tank IME when attempting such a stocking.
It is hard to have a colony in an all-male tank given their breeding strategy
However a group/school of either of the common synos(multipunctatus or lucipinis) is a great addition to most African Cichlid tanks.

Like others have said a 6' tank is much more versatile and would go much better than a 4' tank (especially with venestus).
I just had to rehome my venestus because he was getting too big for my 4' tank. I felt sorry for him :/
