It's highly unlikely to succeed considering the constant state of war between the four main nations of that continent (who would need to keep their warriors). Besides, the Blades aren't as knowledgeable on Akavir as were their (Akaviri)Dragonguard forebears and the Akaviri Potentates. An example is in the failure of Uriel V's invasion of the Akaviri kingdom of the Tsaici (where the Dragonguard originated). Knowledge was compiled from accounts by the Potentates and what the Blades had left from the Dragonguard (along with whatever other source the Empire could get to).

So unless the Nerevarine has remained loyal to the ideal of the Blades (the one where loyalty to the Dragonborn or his heirs takes first precedence), and managed to attain a base from which to draw an army, the Dragonborn's prospects in Akavir seem a bit dim. Then again, if Akaviri magic is just as weak to the Thu'm as Tamrielic magic is to it, then perhaps the Dragonborn could just bludgeon and destroy whoever defies him or her.
