So I was thinking about this recently and decided to see what you guys think. If Aurelian had re-built the Roman walls to something resembling the Theodosian walls (of course the Theodosian Walls don't exist yet so he doesn't have a model to go off of), what effects would this have?
Assuming things go the same way as OTL, I imagine Alaric would not be able to sack the city, and neither would Geiseric. Also, this would butterfly away the increasingly growing importance of Ravenna. Since Rome is now a much more defensible position than it was OTL, there wouldn't be any need for the imperial court to hide in Ravenna instead of Rome.
Thoughts?
