I would think it really depend on the gap between a Heavenly Dragon and a Great Dragon King should be the biggest factor, because you having beings like Ophis, whose stronger than Indra, ranked as having power about 25% more power than x2 a Heavenly Dragon's, so about 2.5 times.

In other words, if you combine all five/six Great Dragon Kings, perhaps using Outrage, how does that compare to that kind of math. Is that less? More? We simply don't know right now.

My guess is that its not enough.
