No, you don't go that in-depth until it's actually been chosen for development.
The initial concept is one or two sentences giving a very general idea of what the game would be like. The idea is something that will intrigue the boss in the time it takes to ride in an elevator with him.
If that works, then you're told to expand it into an actual design document. If that is accepted, then development begins.
