I stand by my precedent post: losing a battle is not enough to cancel a religion.
Costantinus legalized christianity because it was already a religion with a lot of followers, not out of kindness. The following emperors used christianity as a way to unite empire, just like the third century emperors tried to use the solar cult.
I don't think that you could do more than Julian to restore paganism. The actual key to dilsodge christianity is to have another religion with the same appeal to the people. After all christianity prospered notwithstanding three century of persecution.
