Future (ambitious) project?

Have recently been looking at the products that I am selling (and still in production to go on sale) and one of those random thoughts struck me. The perfact addition to accompany my collection? I dont know - so I am looking for some feedback on this.

I am now seriously considering creating a set of Tarot cards. This would involve me drawing out the design for the 21 picture cards and getting them printed some how. Now the printing is an issue that I can face later on down the line. What concerns me is that I dont really know anything about Tarot (always been more of a Rune man myself), but have not been able to shake this feeling that I need to design a deck.

What are your thoughts on this?

*UPDATE* - Another thought occurs! Seeing as one of my passions and strong points is photography, what do you think of a photo based tarot deck. Obviously it wouldn't be straight forward photos, but rather heavily photoshoped in a typical gothika style featuring all the embelishments associated with traditionally based pagan / wiccan / gothic art.
