Why not? It takes some time to hollow it but if I remember right, it takes 3-4 months making one of those. There should be a day or two in the schedule for hollowing the seat tube. Some manufacturers make two separated halves that are glued together at the end.
Since these bikes are super custom I don't get why they need an adjustable seatpost at all.
Btw, the craftsman usually makes yachts out of this wood.
