Pulled Pork Pancakes
It's really too bad that Father's Day brunch isn't a thing, because if it was, this would be an amazing thing to serve. While I don't know your dad, I do know he'd like this. You can also add maple syrup and butter to each pancake layer if you want to make it even more delicious.
If your pork butt was butterflied to remove the bone, definitely season the inside of that as well.
You can prepare the pork ahead of time and just reheat as you're making your pancakes.
You can use milk instead of buttermilk for the pancakes, in which case you can omit baking soda.
