I don't think the width of the planer has much to do with it's ability to handle short stock. Anything under 12" is a challenge to run through any planer. I'd make a carrying sled for this purpose. Also, CA gluing the piece to the sled (using blue tape between each piece and the glue) is a safer way to prevent snipe or grabbing.

I had the DW735 for years. It's a great planer, but if I had the 20" I wouldn't be looking to get another. I do wish for a drum sander at times... That's a horse of a different color and very appropriate for smaller, thinner, daintier things.
