Feral Combat Training: Choose one of your natural weapons. While using the selected natural weapon, you can apply the effects of feats that have Improved Unarmed Strike as a prerequisite.

Dragon Roar: You gain one additional Stunning Fist attempt per day. While using Dragon Style, as a standard action you can expend two Stunning Fist attempts to unleash a concussive roar in a 15-foot cone. Creatures caught in the cone take your unarmed strike damage and become shaken for 1d4 rounds. A successful Will save (DC 10 + 1/2 your character level + your Wis modifier) reduces the damage by half and prevents a target from being shaken.

Dragon Roar has Improved Unarmed Strike as a prerequisite. So,

Can you roar with your natural weapon instead of your unarmed strike?

Sure can!

That said, there's no reason to do so if your natural weapon is weaker than your unarmed strike. Therefore, not a great option if you're a monk or brawler.

"While using the selected natural weapon.." i would argue that you are not using your claws when activating dragonroar, and feral combat training does not apply.

16d6 from Carnivorous crystal ooze form and Strongjaw spell. It is a good anti-swarm tactic but usually it is better to full attack.
