The coach sounds like he wants the new bat to do his job - that is, teaching her how to hit for power. Ask him to suggest some hitting instructors to add pop since he obviously doesn't know how or want to do it himself.
I could be wrong but I don't think that's the situation. She's been going to the same hitting instructor for the last 2 years and has steadily increased in power. I think he just wants a little more pop.
