I don't think that would be a wise thing to do.  The motor firing has be
done at a precise time with the spacecraft in the proper attitude.  If the
hammering was done during the motor firing, and the antenna was to pop
open, it could change the spacecraft attitude enough to really mess up the
orbit insertion.  Besides, the spacecraft will very busy as it is during
the orbit insertion, collecting the probe data, performing a 1000 km Io flyby 
and collecting science data on Jupiter.
