It's not about artwork (though it would give people a chance to showcase just how easy it would be to improve on the artwork they put on the official set).

It's about downloading something (which isn't a pirated movie) and sending off something as an endorsement of an idea.

You could have spaces for missing discs (like the HD restored OUT, the theatrical PT etc).

You could even have downloadable representations of the discs themselves which could be printed onto or stuck to cardboard.

It's saying, if this exists (for real), I will pay for it.

Just like the Kenner set was a virtual Christmas present because there weren't enough figures to keep every child happy on the big day.
