One final suggestion:
It might be nice to add some extra merc units, maybe including some Valyrian/Free
Cities units (which weren't particularly 'Free' at this point yet, but did exist) such as Myrish crossbowmen or some (to be devised) advanced but relatively cheap Valyrian units for the Targaryen faction. At Dragonstone a unique recruitment building, similar to those used by Byzantium in the Stainless Steel Mod, could for instance be placed. This would make the 'early' Targaryens a bit more different from their Andal neighbours and confer an advantage to compensate for the lack of dragons.
