Hey let's not forget the creativity and passion approach. It's difficult to make the mountains fit in, but not impossible. If someone loved their WH20 and never wanted to get rid of it, and they had the right resources, they could (if they have great artistic skill) photoshop a translite with white mountains, photoshop white mountain cabinet art and photoshop a white rock playfield. I mean, there are people who are making complete custom themes for some machines! This is just a slight edit of a previous theme. It's definitely possible, just not at all cost effective. Aside from the original art, there isn't much really that would be incompatible with the theme.
