Pushing bedtime back?

We want to be able to eat dinner together as a family, but we usually don't get home until 7pm and DD has be going to bed around 8pm. That means we start her bedtime routine at 7:30pm which doesn't leave us enough time to prep, cook and eat.

DH was thinking about pushing DD's bedtime back to 9pm to give us more time, but I'm hesitant to mess with her bed time. She currently sleeps from 8pm-6am with (relatively) minimal fuss. What would you do?
