For me it's debatable how long it's still physically sound as dyes and stains are quite penetrative as opposed to lacquers, the latter being more fitting to be simulated by clear-coat.
Also, since most lacquered woods are both (or all three) dyed/stained and lacquered, the Physical Material would need multiple clearcoats and definable thickness (Maxwell had that kind of shader), so with CoronaPhysical having just single, you would have to go to CoronaLayered material again.
This would be well worth the research.
