Armenian passport is definitely an interesting option - both geographically and geopolitically detached from most English-speaking countries. 

The CBI requirements are not as cool as you mentioned, but they definitely came up with creative investment options. 

There policy draft included things like: 

Founding a tech startup with over $1 mil valuation.  
$100k investment in a venture capital fund. 

But I never got the final CBI documents yet. 
Let's see

What do you think of Armenia’s investment citizendship? Yes it’s a 100k for a not as good passport as Caribean ones, but that money can be held in the stock market or in a bank account, and then withdrawn after 5 years (I think). And it’s a pretty good back-pocket / plan C/third passport as it is uncorrelated.
