September, it is a lot easier to get them to pull you from the "to be read" pile than to resurrect you out of the "rejected" pile, (assuming the worst of course). Probably not much downside to doing this. If it goes poorly, just don't become one of those persistent applicants that need to be told "no" over and over. I'm OK with one reconsideration request, but I have had four and five before. After two, we tend to entrench more into "hell no, you are dense and annoying please stay away".
I agree with OPD, if you have a reason for your interest, this will often work. If it feels more like sycophantic dribbling, not so much. Good luck.
