I often think that's the sort of vision I'd like to have. However, what I've found is that it seldom comes to me (but, sometimes, it does). Sounds kind of like your world, Steppe.
What happens more often with me is that I find a word, a phrase, or some nebulous concept (say, "I want to write a sestina") that turns into something, that takes on its own life and form as I go.
If I could be sure which approach was more successful - or even more fun - I might stick to it.
My mother the Ph.D. often reminded me that, for every truth, there is an equal and opposite truth. In that light, I'm reminded of a quote I saw a few months ago. It said, in some form, the following: Inspiration doesn't always come when it's needed; therefore, a writer needs a plan for dealing with the intervening time.
I'll dig up the exact wording and source of the quote.
