Can changing the genders of your sims mess up your game?

Not sure why I started doing this (it's just fun). Using testingcheats and the CAS.FULLEDITMODE I enjoy going into my households and changing all my sims' genders and ages and watching the chaos that ensues. But I'm wondering if this will cause real chaos in my game? I'd assumed as long as nobody was pregnant it wouldn't make that much difference and having a parent that is younger than their child shouldn't cause the game to go bonkers right? LOL I turned the Goths inside out. Bella became Bela and Mortimer is now Tima (Mortima). Alexander is Alexandria and Cassandra is Cassanova. Clearly I have too much time on my hands.
