No, not in case of the launchpad configuration. From the original launchpad.ini:

;;; hotkey actions are defined below as <key_sequence> = <action_command>
;;; one action definition per text line.
;;;
;;; <key_sequence> is a blank separated list of key symbolic names. See keydefs.ini for details.
;;; <action_command> describes the action to execute on a particular hotkey sequence.
;;; Currently three type of action supported depending on the first character of the
;;; command string:
;;;  '!' -- shell command. The <action_command> string excluding the leading '!' is sent to the
;;;         system shell, exactly as it was typed from the console.
;;;  '@' -- Kindle Framework script. The <action_command> string excluding the leading '@' is interpreted
;;;         as a name of a special script containing command information obeying format of
;;;         the known hotkeys package. The main purpose of these scripts is to simplify
;;;         entering special symbols into kindle Framework search box
;;;  '#' -- Kindle Framework key sequence. Similar to the above, but doesn't require
;;;         external script.
;;;   all other command strings are interpreted as a sequence of a send_key commands. The contents of these
;;;   commands gets interpreted and sent as a sequence of simulated keystrokes to the input subsystem.
;;;   Such commands consist of the space-separated tokens, which can be symbolic key names and/or
;;;   ascii strings enclosed in quotes (")
;;;
;;;   Note: to correctly accept  kindle key sequence starting with a special
;;;         symbol, the Framework search box should be brought up, if not already.
;;;         Press the 'Del' key on Kindle in order to bring the search box up

As far as I can see in the launchpad code, the "#" sequence uses the "sendkey" command, whereas the unqualified sequence will actually send keystrokes to the input subsystem. So - just remove the "#" and the apostrophes, I think:

W = FW_Up
X = FW_Down
A= FW_Left
D = FW_Right
S = FW_Press

should work, I think.
