Designing a "console"

Now that I have two working MIDI manuals, I started drawing up plans for the console. I plan on using 2x4s for the frame, and using mending plates (perhaps) to hold it together. Here's the side view, front to follow. The M-Audio Keystation will be nestled in under the massive Novopiano:

The front-to-back distance between keyboards will be to the AGO standard, but not the height. Also, the width of the keys is not exactly the same between the two :P A good reason to spring for a second M-Audio sooner rather than later.
