What happens if you destroy a Dungeon chest that hasn't generated loot?

1) What happens if a Dungeon chest that hasn't had its loot generated gets destroyed?

2) Assuming it can be picked up, once it's placed again, would it still try to generate loot, or would it become a normal chest?

When you interact with the chest (opening, breaking, using a hopper to insert/remove items, using a comparator to get signal strength, or using a dropper to insert items), it will generate the loot and allow interaction (which answers the second question as the chest broken will just be a normal chest and the loot will drop on the ground).

Wait it out, dungeons have good loot. Make a path up to surface and try to loot resources from the area. I once destroyed a chest that I hadn't looted yet and got nothing later. If the items come they will most likely despawn unless you afk there.
