Well it is semi-democratic so you wouldn't neccesarily need a revolution, if you could get a more reform-minded government elected making it more democratic so you could elect a government more to your liking. However that is very unlikely to happen in such a society. Your revolution wouldn't be too succesful either for this reason, even if you somehow succeeded you couldn't stay in power without a secular dictatorship like the Shah's Iran.
Well, like I said, I think my best chance for success is to work with religion rather than politics. Reform that and you'll reform everything else in such a society. If it came to violent revolution, I'd probably have to install myself as a dictator for a couple decades, making gradual reforms that would affect each new generation, eventually allowing for a more democratic state.
Probably.
