It sounds like you want the homebrew. So do it. Homebrews are the best worlds to play in, as long as you have the time and patience to devote them. They become yours and your players' far more easily than published settings. So do it. If you're not ready, take a while longer in FR. Build a nice long story arc leading to the PCs going to your world, let them rap some things up before they go. This buys you some time to get some basics ready. Good luck, and have fun!
