I mean, that's kind of the point? Exalted has never really shied away from how messed up the "Great Man" narrative can be, and if I was going to pick anyone to be a secret Solar King in WoD it would be him.
Thing is, as much as Exalted doesn't shy away from the Great Man narrative's problems, it does so from the perspective that the Great Men in question really are that Great. The troubles, in Exalted, arise not because they're incompetent, but because they can be corrupt and because, despite their longevity, they are not eternal.
A Solar God-King in WoD would be leading a comparative utopian paradise, even if it were oppressive and intolerant, because everyone in it would agree with him and be genuinely happy to be working for The Glory Of The Great Leader. So happy to do so that they achieve actual fulfillment in self-sacrifice and dedication to their tasks, even without more reward than their Great Leader chooses to give them. Further, the Great (Solar) Leader would be brilliant enough, and have a smoothly-running-enough bureaucracy with sufficient efficiency, that everyone would genuinely have sufficient to thrive on. The combination of a sense of fulfilment from simply working for the Great Leader's goals, the efficiency of the magically-run bureaucracy, and the lack of corruption (it's not corruption if the greed of the Great Leader is openly presented as him taking his due) flitting away resources from things the Great Leader intended them for would mean that there's plenty to go around, and that everyone has equal (except the Great Leader and his coterie, who have more because that signifies his greatness and grandeur, and those in his coterie are happy to be ornaments for it).
In other words, it would magically make the Great Man narrative work perfectly well, if horrifying in small ways regarding the humanity and individuality of the peasantry, at least as long as the Great (Solar Exalted) Man was running things.
Where real world issues arise due to people not feeling like working is worth it, or the corruption that steals the labor of others for themselves leading to shortages and more graft and laziness, and ineffective leadership on a large scale because the leaders are just men and not Exalted God-Kings who know all and can really manage it all personally, the Solar Exalt, being a Solar Exalt with the right Charms for it, could really make it work.
That it still falls apart eventually because his own callousness means he stops CARING for the well-being of his people, except possibly as cogs in his machine, and thus has them become more and more dissatisfied because there's only so far magically-imposed ideals can make self-sacrifice seem worthwhile (at least without the Solar RIGHT THERE imposing UMI), is the narrative of Exalted. Exalted attacks the Great Man narrative's conceptual core by allowing the Great Man to exist as Greatly as a designer wants, and then demonstrates how things eventually break down anyway because even the Greatest of Men are still...men.
