I have tried this yeah. I noticed on a custom mods site someone here posted recently that they did woodgrain / leather mods for the internals of the EA. I decided I'd see how easy it was to do myself.
I picked up a centre console piece from a wreckers to experiment on, I found that the woodgrain was the shitiest thing to do, since you couldn't really attach it to the current console without adding a lot to the size and weight, and I wasn't too keen to cut pieces out to replace with wood pieces and hope I could cut the wood to match.
What I did in the end was get some "fake-woodgrain" sheets from Spotlight, they're mainly used for kitchen cupboards or wooden tables that have scratches you want to hide, they look realistic and just stick on to a surface like wallpaper. The overall effect with the woodgrain sheets and the black koskin (leather look-a-like) didn't look to bad, but I felt like putting fake woodgrain in the car would make me feel too pretentious.
