Eltab
Lord of the Hidden Layer
If Cormyr is not going to be the "Imperial Cormyr" from pre-Sundering, then the core Kingdom will be surrounded by allies - think 1945-1990 USSR and the Warsaw Pact nations.
Not necessarily willing allies, and maybe not able to really do much on their own, but when Cormyr Speaks, they will listen and they will follow suit.
This, rather than the Cormyrian noble houses, is where I would place a lot of "seditious plotting and rabble-rousing".
And, not being inexperienced in the art of political intrigue, Cormyr uses the Minor Ally governments to provide support to pro-Cormyr forces in other nearby lands. Plausible deniability, you know.
