Parents: Would you let your child do this?

Ok, first off I'm 15. My parents are letting me do this acting thing over the summer. It involves me staying out until 2am but I'm in good care and for the performances my father has to be there anyway. Now my dilemma is that I want to do this during the school year too, and I know that this seems pretty much out of the question but let me give an argument. The performances are only on every other weekend, on Friday and Saturday so I would not be missing any school. I would make sure my grades don't slip below an A or I would promise to quit. I would show my parents all my homework so they could see it was done and that I wasn't slacking off. The rehearsals are on Sunday, but are only until 8. I usually don't have anything outside of school so this would be a great thing for me to look forward to and motivate me to do well in school. So that pretty much concludes my argument. What do you think? Would you let your own child do this? If not, why? Thanks in advance.
