I'd love to see a controller keyboard with a flat top big enough to hold another instrument or module.

At one time there were instruments that allowed "stacking" (RD-300, Rhodes, Wurly, Polymoog to name a few) and I'm sure with today's technology, a lightweight 61/76 note controller could be made with a strong enough top material so that we could put an instrument like the microARRANGER (or even an S910, GW-8, or PA-500) on it and have a better feeling and/or extended range keybed to use and not need to use a fiddly and inconvenient (and often wobbly) double tier stand.

I think it might even sell well....I know I'd buy one in a heartbeat.
