Do you mean just using her healing magic to heal the wounds on Irene's original body.

Well, if Irene couldn't turn her back into a full human or give her sensations back, I doubt that with Wendy's enchantments would do anything different. The whole point of this was Irene getting a new body and leave her old defective one behind.

Well from the poster, Natsu still has the bandages on for the FDKM, so this is before the Alvarez Arc.
