That's the direction I'm going. I've got two 1/4 bbl's that I'm going to use for 6 gallon batches.
OP, I was going to suggest a 4" TC flange welded to the top (bottom) of the keg with a cover could give good access, but honestly, I don't think I would cut and weld on a sanke fermentor at all since it will be impossible to get a sanitary weld on the interior.
I think I'm going to make an angled nozzle for my pressure washer for cleaning, and just go in through the valve hole.
