Thanks for all the ideas! I'm considering putting the jointer on the long "bottom" wall near the tillering tree even though it will be next to impossible to efficiently get DC to it. Moving it along that wall will let me tweak the position of the table saw and router. The jointer is just a HF 6", so there's very little sticking out from the fence, but I could always steal a few inches from that wall if I ever upgrade to a larger jointer and need to box in the protrusions from the fence.

I'm also really liking the idea of closing up the garage door and replacing it with a double door and 1 or 2 windows. Even my wife likes that idea, so there's a much better chance of it happening

I picked up a used Jet DC-1200 dust collector this weekend (and the guy I bought it from threw in a 12" delta planer for next to nothing), so I now have the DC covered!
