I'm wondering if Simon might have both occupied it, then later razed it once he no longer felt it useful (as it would have been inside other fortifications)? If Ben-Dov has identified the correct foundations, then it does seem to have been razed during that general period (overbuilt with a residential quarter in the Hasmonean period, which was later leveled by Herod for construction of the street and plaza in front of the new Temple platform extension). But, whether leveled by Simon or afterwards, I haven't seen any published finds narrowing the destruction date beyond "latter half of the 2nd century BCE". 
The Second Temple Period article has been sitting on my watch list for some time, as I had been thinking of contributing to it myself. I was very relieved to see you contributing a good number of edits to it, as I haven't had time.  talk
