Is there evidence that Arius "reformulated" his Christology post-exile?

I realize that it may not be completely possible to answer this question given that so much of what Arius wrote has been lost and/or misrepresented by his opponents. However, I have read his few letters that remain and his post-exile letter to Constantine doesn't seem much different than his others. I don't have access to the [R.P.C. Hanson](https://en.wikipedia.org/wiki/Richard_Hanson_(bishop)) 's 1998 book [The Search for the Christian Doctrine of God: The Arian Controversy, 318-381](https://www.amazon.com/dp/080103146X) (reissued, 2006) so I'm hoping someone here who does can provide further insight. Here's the quote that leads me to the question: >Though he never repudiated the council or its decrees, the emperor ultimately permitted Arius (who had taken refuge in Palestine) and many of his adherents to return to their homes, once Arius had reformulated his Christology to mute the ideas found most objectionable by his critics.
