Yeah, from the looks of the pictures, your corm is mostly unaffected. The corm is like the brains and the battery for the banana. Keep the corm healthy, and best case scenario is everything goes back to normal. Worse case, you get a couple of pups.

You can find videos about professional banana farmers who remove pups from parent plants, chop off all the roots, and replant the pup further downfield. It quickly adapts and takes off on it's own, so long as it has enough corm to weather the change.
