I know it's out of historical time, but please make a DLC where you restore the Roman Empire and have some special features for it.
Basileus: Restore the Roman Empire
Yea but those will be probably events only, and i'm asking for something more like the old gods that provide special features for nords
In any case, you can restore the imperium in CK2 and then convert your game to EU4. Your empire will carry over.
