Here’s the tested solution. http://www.unicyclist.com/forums/showthread.php?t=42679
Quick and easy with a Fusion cover. With the Gel seat you’d have to take out a few staples. Then find a way to reattach the fabric. I think there’s a KH freestyle front bumper that might work. Or maybe restapling. Might be easier to just get a Fusion cover. They stretch down well on the thinner Gel saddle.
