It does sound different and potentially interesting, but I find the motivation of overthrowing the monarch for the sole reason of democratic desire kinda far-fetched. I can imagine a band of rebels trying to take over for personal gain, but I'm having a hard time figuring out how to get an entire country to turn on a ruler with a reputation like that. Is there any other motivation? Do people want revenge for the suffering of their forefathers? Are evil princes lining up for the crown? Are the queen's restoration efforts taking too long to please the people? Has a neighbouring country flourished shortly after a similar revolution? Do people still hate other provinces and clans but are prevented from going to war with them under the unified rule? idk, I guess what I'm trying to say is; are there more details to your idea and setting yet?
