You'd have to do those animated poses only once, to figure out the correct key values.

Once you have those key values, it's easy in Python to repeat them from a starting frame to the last frame of the animation, and it's also easy to specify a stop frame.
It's even fairy easy to mix different breathing types, say 75% normal breathing +25% panting, or 40% panting, 40% scared. Building a good user interface is another matter though.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
