Hmm, well, that Paua sounds/looks pretty cool.

But....if it's going to cost you over $200 for just a sheet of it, why not just buy another Dovo MOP (~$250, right?), and use the scales off of that?

Take the Dovo blade and put it in the scales that are currently on the LeGrelot, and then you can sell that razor off to defray the cost? Or keep it as a travel/backup razor?
