If you have limited space you have to be pretty vicious about what comes into it and stays. For a general all round metal working shop one mill (BP is perfect), one DP, one lathe (big as you can fit), bandsaw (horizontal or vertical), hydraulic and/ or arbor press and ideally a welder of some sort.
You don't need 2 DPs, so get the biggest and best one you can and sell any others. You don't need the Logan as the Southbend sounds like it's equivalent and has the ability to cut different threads without buying anything extra, so sell the Logan. Someone else will get great use out of it and be happy to have it. You don't really need the horizontal, but if you can squeeze it in it adds some capability that complements the BP. You really don't need that bender, so don't get it.
It's easy for this hobby to turn into the metal equivalent of collecting baseball cards. nothing wrong with that if that's what makes you happy, but you'll need to find a nice warehouse to rent if you plan on keeping it up. If you want these machines to use them to do stuff, then you have to figure out what you want to do and get the stuff that lets you do that. You clearly have the skills and contacts to do so, so make a plan and stick to it and you'll have an awesome workshop in no time.
It's kind of what I've done (just without the plan) and I now have a capable workshop that I use pretty much every day to make all sorts of things. As time goes on fewer of those things are about fixing the tools and more of them are actually useful outside of the shop. I'm at about 50:50 right now, forcast of 70:30 in about 10 years
