Whilst the title is more for flair, I was wondering what feasibly could be done to bring Amalfi to dominate S.Italy after 839. Particularly dominate S.Italy, whilst being at least nominally part of the Empire.
Ideally I'd love to see the Prefect of Amalfi be the regular Katepan of S.Italy, but that is more bonus points.
(I apologise for the lack of details, I'm very short on them myself!)
