Wow, that would scare the cr*p out of me, on the way home!!!! That actually doesn't seem to be a legal connection to me, with clearing customs. If you want to make it for sure, I definitely would do only carry on bags. And that still is no guarantee at all. AND I would definitely look before you leave home, as far as your options to get home the same night, if you miss the connection.. Often the people at the counter have no idea what the options are to get you home, if you miss the connection, especially on other airlines. Best wishes..
