Hutchentoot has its own package, doesn't it? Why not modify the
package definition

(defpackage hutchentoot
  ...
  (use :gray))

This will import _all_ of Common Lisp, with CLOSE and other functions
overwritten. It also has the advantage that it does not trick the
compiler. Your change is not allowed and the compiler does not expect
it, so it will keep using cl_close(), etc, which is fine, it will work
(ANSI CLOSE will call Gray CLOSE if it finds a standard-object as
argument), but I would not call it the right way.

Please tell me whether this works.

Cheers
