I also find a certain fascination with coups... there must be coups everywhere in this timeline. But one funny thing about coups... the majority fails. You need to muster significant support for a coup, and the locals need to support you, at least at start, or you need to have a powerful backer (like the Red Army in early post war Europe).
That's actually one of the problems I, too, have here.
In my view (also being a historian) history is whole lot more about complex processes and chains of interlocking causes and effects, rather than a succession of cataclysmic breakwater events, with Big Leaders making Big Decisions.
Certainly that aspect does exist as well, to a degree — but even the Maximiliens, Vladimirs, Maos, Ches, Fidels, Ruhollahs, etc of history are to a great degree slaves to and bound by the contexts they find themselves in. They are, each of them, an Effect following some series of Causes that preceded them.
Suspending history on a chain of successful coups is ... well, romantic in a certain sense I suppose, but not very ... historical.
