+1 on the cold water and chiller re-work...reuse or repurpose. When I made the upgrade to a keggle, I tried stretching my chiller out for better chilling distribution through the wort. My IC was given to me and was only about 25ft, 3/8" dia.
This spring, I bought a pump, built a 40ft IC, used the old IC to prechill, and began whirlpooling. I have not seen the amazingly quick cooling times that others have attained, but it works BETTER than the IC by itself for sure.
That said, I would only consider going with a plate chiller/CFC if I build a hopback.
Another issue I had using gravity to drain was getting that last bit of wort out of the keggle to fill the second fermenter...the pump truly rocks in that regard.
