Agree with Trin's post. That's exactly what India was like, at the time, and many of these varna-based cliques exerted a powerful influence on the administration. It was the powerful and wealthy Vaishya guilds -many of which had levies of their own- that fuelled rapid expansion of the Chola state, as well as the spread of Jainism in the later medieval period. Brahmadeyas -land grants to brahmin families- lent the ruling dynasty a great deal of legitimacy, prestige, and were regularly undertaken and recorded on copperplate inscriptions to ensure the king stayed on good terms with the priestly class.
If I'm not wrong, this was implemented in one of the two most popular mods for EUIV, and worked pretty well. My only concern would be with societal change, and a means of dismantling internal factions should, say, the government type undergo a drastic change. I wouldn't want to have to spend all my time appeasing obsolete, archaic power-hungry aristocrats in a communist-ruled utopia.
