I think that as long as it has grounds settings-wise there would be room for that kind of upheaval. In the past, many of the attempts have failed because the players behind them were not familiar enough with the history of Yliakum. So they wanted to "save the kingdom" and whatnot when there's no such thing in PS. I suggest you take a little time to get to know how the government works (perhaps you've already done this, I don't know), what kind of problems would arise from that system, and how these would motivate your character to take action. Also, try to meet characters ingame who can join your plot.
GMs don't get involved in player events but I'll be happy to offer advice if you need it. Good luck!
