Interesting idea! Gotta try it when I can get ahold of a brush.
For people looking for a wood texture, have you considered drybrushing it? Give it a dark base coat (or use a black case) and then paint lightly using a lighter color with a brush that's almost dry. The paint will only stick to the raised areas, highlighting the texture. Do it with multiple colors of varying dryness to increase the effect.

Notice how the wood is darker in the cracks?
I'll do some experiments if I can find the materials.
