I seem to recall that there is a program on CBTTAPE that can call IDCAMS or 
IEHPROGM but intercepts the and ignores the ENQ on the dataset to be renamed 
(or deleted). There is a certain danger to it, so it performs a security check 
to try to restrict it use to only those who are authorized. I have used this in 
the past to re-allocate perpetually allocated libraries on a cloned sysres 
volume. And I have used it in circumstances such as the OP brought up. Just use 
with extreme caution.
