Cool idea? Stupid idea?

Do-it-yourself tarot decks.

Here's how it works.

1. You create or find digital images appropriate for the tarot deck of your dreams. Draw them, scan them, find them on the net. Whatever. Using image-processing software (e.g. the GIMP freeware package), crop / rescale to 600x900 pixels or 1200x1800 pixels.
   
2. Digitally add an overlay (provided to you) which adds borders and the appropriate text to each image.
   
3. Print the images as 4"x6" pictures, either at a digital photo-printing place (around 19 cents per image, hereabouts) or on your own equipment if you've got it.
   
4. Print a back-of-the-card pattern (provided to you) on each card. You can do this with a laser printer.
   
5. Laminate, using (for example) librarians' book-covering film.
   
6. Trim the edges.

Things come out looking something like this.

Cunning plan? Really bogus, for some reason which I (not knowing much about tarot) am missing? There'd be a certain amount of time and work to prepare the pictures, of course, but what else?
