As I explained in my previous mail,
it would more be something like what follows (wholly untested),
where in your code you'd
(1) call the register function initially
(2) use load-slime-override-sysdef instead of load-sysdef in your code.

(in-package :asdf)

(defvar *slime-override-systems* (make-hash-table :test 'equal))

(defun sysdef-slime-override (name)
  (values (gethash (coerce-name system) *slime-override-systems*)))

(defun register-slime-override ()
  (setf asdf:*system-definition-search-functions*
        (cons 'sysdef-slime-override
              (remove 'sysdef-slime-override

(defun load-slime-override-sysdef (name pathname)
  (let ((name (coerce-name name)))
    (setf (gethash name *slime-override-systems*) pathname)
    (load-sysdef name pathname)))
