hello sir
first, your post is very technical; i am worried that your talent has not find a corresponding creative one yet. solo projects rarely get finished. my suggestion is that you showcase your work, make it appealing, and launch a community project. maybe offer small amounts of royalties and find like 10 People who give you what u ask for. set a theme, set design guidelines to make the designs match and you might have a great project here.
keep in mind that there are a good portion of designers out there who lack the technical skills to develope a game. also, ideas are cheap, do not let somebody run you over with their imagination and visions. you should lead this project and the designer(s).
