Well, one of my first timelines was an attempt at this.
The first and second versions can be found here:

Some notes I had for later events:
-Christianity would remain a Mediterranean/Middle Eastern religion + Ireland, while Invictism would dominate Northern Europe
-The Gallic Empire would fall, eventually, resulting in Vandal Italy, Burgundian Gaul, and maybe I was going to throw the Lombards into Spain, I forget. Britain would remain Sub-Roman and develop similar to OTL's Byzantine Empire.
-No, wait, it was the Franks who were going to go to Spain, and then Africa. Then the Lombards show up.
-I've since forgotten were else I was going, or even if I had a set plan
