It would be a mistake to include Transilvania as an independent or a Romanian facton. The province of Transilvania has been ethnically and culturally Hungarian (or Magyar if you will) throughout the entire medieval period. When it was independant for a while, it was only because the rest of Hungary was lost to the Turks and the Habsburgs.
Otherwise, including Wallachia as a faction may not be a bad idea, I mean they were there and they did fight off the advancing Turks on many occasions.... but of course this is up to the developers of the mod who have to look at game balancing issues etc.
Also another note; Romanian historians like to hijack Hungarian historical personalities by changing their names and pretending they were Romaninans. Especially if they accomplished something noteworthy. If this mod is intended to be a total realism mod, it would be a good idea to ignore the Romanian version of history of that region as a reference.
