It may be difficult to find a stand that meets your requirements and still have a small "footprint". In a similar situation, I have used a triple keyboard stand. Then cut a board to fit the top tier to hold your music. You can even clamp a lamp to it to illuminate your music. This setup can be tilted slightly toward you, and will hold several books at once.
On a related subject, I have had real difficulty using the PSR2000 music rack. If I wiggle the keyboard much at all, I find myself picking the rack, music book, etc., up from the floor.
