n80krr - welcome to the forum mate!
Sounds like we have another bat tinkerer! The method you are looking to employ for laminating a bat will be extremely difficult for many reasons i wont go into. It may be easier to go for a cruder lamination to start with and see how it goes?
As for that slither of willow, it might be worth asking some of the batmakers on the forum - Matt at Hell4leather, Andy at SAF, Dan at Vantage or Gary at Redback all might be able to help you with this one.
