Swapping Hamilton tickets for earlier date?

Hello, I'm visiting a friend in Chicago from Australia between October 17-27. I scored tickets to Hamilton on October 25 but the friend I am visiting has to go to DC for work from October 24 and unfortunately will not be able to make it . Our tickets for Hamilton are mezzanine, row G for two people. Is there anyone with similar tickets for an earlier date say between October 17-23 and willing to swap? I woke up at 1AM Aussie time to get these tickets so I'll be damned if my friend has to miss out on the show!
