Do you have any other grounding to your theory other than "I don't think"?

I mean, that's a nice theory bro but what is the basis for your theory? How can Haoshoku Haki control the weather? Why can't Dragon just have a DF?

All I can say is that Dragon's power is probably DF based and that both him and Garp (or at least one of them) has Kings haki. I'm not sure what else are you looking for.
