Considering that he was unable to even eat the god flames without emptying his own magic first, I think it's highly unlikely that he can produce new god flames.

To me Dragon Slayer and God Slayer magic seems too incompatible to work together like that.

If I'm mistaken, I hope Wendy and Chelia will do a little power exchange so that both become the ultimate sky sorceresses with both the Dragon and God Slayer magic.
