Well if nothing else, you'll probably at least want a hatch there for bilge access. You're probably right about maybe needing the trim tabs. My V20 CC has two hatches in the rear cockpit right in front of the motor well. One is really just for bilge access, the other has a liner and drains overboard.
As for posting pics on the Wellcraft site, Tim posted instructions on how to do it. You just need to have the pics on a web photo host site like Fishingworks.com and attach the URL. or you can send the pics to BigShrimpin there and he'll post them for you.
That's going to give you a lot more room in the cockpit.
