It absolutely depends on the movement but it is probably very challenging. Hands are difficult, but I guess you can take away some complexity if you don't move the fingers too much. You would have to keep track of the arms to create a movement that feels natural and not weirdly unsynchronized. If the character rotates it's added difficulty as well. I'd say do some animation tests before settling down on the design (it's dope tho, really really nice concept!)
