How hard to make attack animations with pickaxe the same as the idle one?

[fallenmystic]

As you might have noticed, I'm making a mod which deals with a forced labor in a mine. I wish I could make the player to attack the ore instead of activating it, because with the former I can adjust the attack speed in conjunction with the stamina level, and I suppose it might also give the player more immersive feeling.

 

But it seems that the current pickaxe is an one-handed weapon, and all the available attack animations look too aggressive/dynamic to be used in the context.

 

How hard it would be to create a two-handed version of the pickaxe, and replace its attack animation with something similar to the default mining idle(IdlePickaxe)?

 

Thanks
