We've released a mini, mini mod with a limited selection of units to allow modders to view/use the anims and skeletons we developed for PKH on M2 (as we've moved over to developing the RR version).
Its released as a resource here: https://www.twcenter.net/forums/showthread.php?817399
You can play with the units in custom battle as Normans versus Saxons but I've not attempted to balance the units properly so stats are probably awful. If anyone wants to have a go at fixing the stats I can update the EDU!
