Help making a 'Form Roman Empire decision'

[Pious Agnost]

My current Byzantine game has gone very well, I hold almost all of modern Italy (Ending at what Ferarra owns) I have 2PMs Bosnia and Transylvania as my buffer states (Don't know why, the states they buffer against are pathetic) the Black sea is a Byzantine lake, and I have annexed Tripoli and the one to it's West, whatever it's name is, I have complete power in my region (Except against Russia, France and Spain, those three are still beasts) But unfortunately I've started to get a little bored with the name 'Byzantine Empire' It's a tad Archaic. This is in Magna Mundi Platinum, btw, so the land seizing was very hard. I was wondering, could anyone help me with a 'Formation of the Roman Empire' decision? I'm pretty sure I could cover the requirements and so forth, but my only trouble would be working the flags and the effects

EDIT: For effects I would like to have reputation reset to 0, the same with war exhaustion and inflation, what? It's hard to gain an Empire like mine in the Fort-Fest, stability-hitting, rebel-rousing Magna Mundi

This is my first attempt (I have simply edited the Italian nation quite heavily)
I haven't done the country file yet

Basically now I need help with two things:

1.) Will this work and should I move onto the country file/s?
2.) How would I correctly make my own country file/s for the Romans?

Pretty impressive Empire to hold in MMP. I would have thought with all that War-Mongering you'd be long dead.

As for your coding questions. Your probably better off asking at the MMP forum over at the Paradox forums. Your likely to get your answer within minutes over there and probably from ubik or dharper.

I'm once again having problems with the Paradox forums, which make me unable to post or make my own thread, last time was right after I signed up, and waiting for a day fixed it, however, I am still unable to post, I'll just have to hope it resolves itself soon, or someone helps me on this forum
