The QlikView Power Tools has a User Manager app which could potentially be used to accomplish your task. You do need to be cognizant of the Qlik license agreement around Named User CALs:
Any CAL used by an identified user may not be transferred to another user, unless the transfer is due to a change in the employment status or work duties of the prior user, in which case there is a 24-hour quarantine* before the CAL be transferred to another user.
*In QlikView 11.20 SR16 and above the quarantine period is now seven days.
Hope this helps,
