It seems like a good idea on paper, but I don't know... I was never a fan of painting things, because it ruined the point of blocks coming in different colors. For example, if we were to say, be able to paint wooden planks any color, then there'd be less of a point of having different kinds of wooden planks.
But if the planks had different patterns and designs, it would be better. Painting them doesn't change their designs, just their color.
