Last days I was tormenting RIchard Bodley Scott with sometimes stupid and newbie questions but now I think I know the way how to make such mod in best way.
My idea is to make two campaigns from one original - one for one side, second for another.
First campaign I take is Italian wars. 7 of 10 its battles are played now from French side so it's good idea to start making French Italian Wars Campaign with editing only battles of Seminara, Fornovo and Ravenna.
If you are interested and can help - please write here. Modding is not so fast process (it's long and sometimes boring) but the result would be perfect!
Here's what work need to be done:
1. Replacing all units on map. The issue with current scenarios is that you can't just invert unit nations on map (at least I failed to do it). So the most common and guaraneed way is to open battle in the editor, remove all units from the map (I draw first scheme where which located), then change sides.txt in campaign's folder in My Documents to reversed (so for human player be able units previously owned by AI and vice versa), again open battle in editor and place all units according to scheme or brilliant memory

2. Finding info on how ex-human player side was acting in this battle and write it here like "Battle of Pavia, Gendarmes stand still first 2 turns, city harrison attacks from 6 turn etc..."
3. Scripting actions above (or maybe you know yourself what actions should be performed) in C-like language.
These actions could easily be done separately and then merged together.
If you have any questions, ask. And let the work begin

First priorities - Seminara, Ravenna and Fornovo to be played as French. Next - 7 other battles to be played as Imperialists/Italians/Spanish/etc.
If you going to do something please write here to aviod multiple persons doing the samt job.
