Unless they have changed the whole process that is not a correct description. I remember reading a couple of detailed articles when they were released years ago. Must have been 25 years or more. Beretta at that time described the system as an inner core of plain stable beechwood or something. Over this was placed a thick printed plastic "sock" for want of a better word. This was shrink wrapped and bonded to the wood. I examined several and they had the finished look you mentioned. I also saw several people show up at the gun club proudly showing the amazing wood on their new budget priced Beretta. All were eventually taken aside by someone who explained their gun to them. None were pleased.
I haven't looked at one or even heard about them in years, but unless the have totally changed the process I doubt there is anything you can really do with them. You mentioned lasers and I seem to remember that the design was lasered printed onto the stock.
I would do some more research before planning anything.
