That's what I do too. If you need more inspiration you might try looking at movie posters and book covers from 1950s science fiction.
If you're doing applique why are you worrying about the 1/4" seam allowance? I don't think I completely understand the question. Your idea of making a full size mockup on paper is a good one. That way you can be sure of placement and scale before you start. It sounds like a fun project.
