Forget the stickwork. If you're paying for ice, I would suggest you have him working on skating. He can improve his stickwork for free in the driveway.
Happened to my kid a few years back, turned it into a positive.
My son has always been a defenseman, he told coach he was a forward, played 2/3 of the year as a forward and learned the role.
Last 1/3 of the year he went back to defenseman and they finished up in a good way.
He was the go to guy for his coach and I believe it helped him alot.
