JORDAN1951'S PROFILE

I am new to making games and want to know if this engine is right for the intended project. I'm willing to learn so if you have any pages with basics overview that would be helpful too.

Its a standard rpg with six characters and I want to be able to tell the game which ones to use when until I get to the point where they all travel together. Once they are together I want the player to have the option to choose who they use to fight. I also have an idea for a stance system, where each character has three stances that alter stats and abilities. If you need an example It is *kinda* like the role system in ff13.

So my question is, can I make rpgm2k3 do this?
