Okay, as I promised the first thing I would do was to mod the Dutch in, I did do just that. I copied the original files and edited the appropriate info for Mali/Mansa Musa in the following files from the Assets\XML tree:
Civilizations\CIV4CivilizationInfos.xml
Civilizations\CIV4LeaderHeadInfos.xml
Text\CIV4GameTextInfos_Cities.xml
Text\CIV4GameTextInfos_Objects.xml
Text\CIV4GameText_Civilopedia_CivLeaders.xml
Text\CIV4GameText_Civilopedia_Units.xml
Then make in the Mods subdirectory a subdirectory 'Dutch' without the quotes and create there a subdirectory 'Assets' without the quotes and in that subdirectory another subdirectory 'XML' without the quotes.
Put the files above in there and add all missing .xml files to the XML subdirectory and to the 'Civilizations' and 'Text' subdirectories (without that the mod won't load properly I noticed).
After starting up Civ4 then I go to 'Advanced' and 'Load a mod' and after the game restarts I can start a game with the Dutch Empire!
I've changed such things as starting techs, favorite civic, city names, civ color (orange!), civilopedia text entries for the Dutch and their leader William of Orange, and leader traits. That's not all there is to do of course, but it's a good start and I wanted a proof of concept
It's much more difficult to actually add a civilization, because you have to be sure to take care of all the dependencies between the numerous files. And maybe there's a hard limit on the number of civilizations somewhere.
Edit: added 'XML' subdirectory to description.
