Think that putting a carbon sleeve direct to the blank would be ok? I have some heavy surf blanks that are almost or are an inch in diameter at the butt ends and I like cork tape on these to keep the diameter as close to the original size as I'm not a fan of fat EVA type handles. I'm guessing it should work just epoxy a sleeve to the blank and thread off of it to finish.
I checked the ends on my carbon sleeve and by keeping them as close to the blank size as posiable and cutting the sleeve when stretched it keeps the ends from to much fraying. Also at the reel seat I can use a wide winding check and over lap the carbon under the seat, Sound Right?

You could certainly do this, but I'm not sure what you'd gain by it. It won't add much diameter (less then cork tape) and seems slightly redundant on top of a graphite blank. But I can't presume to know what it is you're after - cosmetics maybe? If you want to do it, yes, you can certainly do it with good results.
