Workshopping an idea - DVD grab bags

So I have, over the years, accumulated many, many, many, many, many DVDs. Most of them live in boxes in my storage unit and I rarely have occasion or desire to retrieve them. The idea of hauling them to a new place just to not watch them is, frankly, less than appealing.

I thought that it'd be cool to spread the wealth around and make it a sort of weird game. So, like, you PayPal me $5-10 and give me a generic idea of films you'd like (five primaries and two backups). A list could be like:

1. A European horror film.
2. A 1940s comedy
3. A Billy Wilder film.
4. A 1980s horror film featuring a cast member from Spaceballs.
5. A musical.
6. (Backup) An Akira Kurosawa film
7. (Backup) Something with a giant monster in it.

Or a list could be like:

1. Any five movies based on a work of literature, preference for 19th century authors.
2. (backup) Whatever weird archival softcore porn you bought on a lark 10 years ago, preference for being based on a work of literature (there goes my copy of The Secret Sex Lives of Romeo and Juliet).

I'd go through my collection and send you five DVDs that match your requests (on a first come, first served basis).
I wouldn't be able to guarantee that you're getting something you don't already have or that you'll even like what you get. I have a list of standard warnings you could request to filter out: Sexual Violence, Gore, Violence Against Animals, Violence Against Children, Roman Polanski, and Woody Allen.
Would you guys have any interest in this? How much would you be willing to pay for a grab bag like that?
