Have you talked to Laver guys yet? They already have something called Legacy which is quite similar to what you want.
I am not sure if my friend is on this forum. Try aditya mahajan on Facebook.
Spoke to him today. (I previously have had conversations with him a few years ago, and his memory seems quite sharp).He took the specs and the pic of your friend's bat where I photoshopped it to mark my specs. Let's see if he can come up with the design that I have in my mind?This will be an interesting little project.
