Two handed animations for two handed weapons. Possible?

[Felis]

you can visibly see them using their free hand to concentrate aether while casting a spell.

Also to hold a not equiped shield in front of the body, because the animation is exactly the same with one handed weapon and shield

Tome-users also need a hand free, you see them writing, and either way it would look utterly ridiculous to see them waving their book around with two hands.

Holding a book with 1 hand and writing in it with the other hand I would not call 1 hand free.
