I have seen some very nice looking consoles that make the cockpit form fitting, and as one who has built a form-fitting RV-3 cockpit, I understand the desire completely! BTW, I also agree that carbon-fiber one a few posts back is gorgeous.
I have found, however, that in addition to the maintenance access considerations (I used to own a Yankee with a center console, and rudder pedal maintenance was almost impossible with the console), if you plan on long-distance cross-countries, it is sure nice to be able to stretch your legs around. Yesterday I flew almost eight hours into headwinds from east Texas to SOCAL in our -6, and spent a lot of my time with my legs draped diagonally across the cockpit in order to keep from getting sore or cramped up.
One thing you might try that could sound silly - but is worth it if you plan to keep and fly your airplane for years, is to spend a day sitting in the cockpit in the workshop. Set up a TV with some movies, have some drink bottles handy (and maybe something to catch the "discharge"), have your computer handy and study for something....back in my NASA days, we did this all the time - "all up simulations".
You'll have the airplane a long time - it's worth the effort to know how comfortable it will be for YOU.
