That's not possible, unfortunately - There's a faction limit, and it's already almost reached.
To follow your example, the Empire of the French King vs the Empire of the French Nobles would require two factions. Slots that we simply don't have.
HRE gets civil wars, like other factions, if their faction leader get the "King offends the nobility" trait.
