This is the HUGE advantage DC's Atlantis has over Marvel's. At least by reading the Geoff Johns New 52 run of Aquaman only pretty much all of these questions are answered or don't need to be asked. It's a shame Marvel has barely attempted to flesh out their Atlantis in this way.
I wish there was a Marvel wide initiative to restore all of their monarchies back to normal and start making interesting stories about their uniqueness as monarchies, instead of destroying and deconstructing them every chance they get. It has gotten extremely boring.
In short, no. Keep Atlantis as a monarchy.
