Wait for the tympanoplasty
I had a very aggressive infection last year (thats right, been out of water for almost a year and feel like a drowning fish). It destroyed 80 % of my eardrum and was quite painful. I myself would not take the risk of swimming with a perf'ed drum, as this could lead to a nasty inner-ear infection, which in turn, I have been told, can not only lead to pain, puss, and more time out of the water, but possibly semi-permenant reoccuring vertigo. You say you have a large non dive related perferation. This leads me to think there is a large chance of getting water in there. these other guys were lucky as they only had small perferations and healed in a couple of weeks. mine didn't heal in 8 months. I can hear again now with that ear, but will be a few more months healing. Good luck with yours
