Here's something I found via the Alternate History Weekly Update yesterday. It's an AH webseries entitled "The Confederation" in which the Confederacy successfully secedes from the Union (as some kind of "butterfly" of the French beating the Mexicans at the Battle of Puebla) set during a Vietnam-esque war in Cuba.
Here's the trailer:
And here's the fundraising video they posted on their Kickstarter page:
I'll probably chip in some money at some point, but they're going to need more than I can provide to get this thing funded. $50,000. Points for ambition at the very least, but that's a lot of money to be raised in $100 increments. I do like how they're offering speaking parts in exchange for money. Find someone with the right combination of cash and vanity and that'd work.
This does remind me of one of my own ideas involving a disintegrating Confederacy with steampunk air pirates. Cuba plays a role in that world, but it's basically a "bridge too far" the Confederates try to cross in the late 19th or early 20th Century and fail massively.
