I rate Westhoff, but I'm not convinced that Larkey could play the intercept back role, as a mobile ruckman, or as a tall winger like Westhoff does. He's a unique footballer.
While Westhoff is a competent forward, I also think Larkey will have him well covered as a natural KPF going forward.
I hope he comes in and takes Waite's spot next year. There's a lot to like about him and I think he would be a decent foil for Brown. I wouldn't be surprised to see him kick 35+ next year if he played every game in the senior side, which would be a great return for a pick 70-something KPF who still has a lot of development to come.
