How about blasting the wood with a pressure washer?

Even if I found that perfect combination of hard / soft grain layers and water
pressure, it would probably be way too labor intensive. And likely a bit too
rounded of grooves as well. Basically the same problems as sand blasting except
you trade dust for drying time.

Still worth experimenting with a bit though...
