This really isn't a good idea, the internet has a dark history of people asking questions like this on forums with lots of really smart people who treat it like a fun challenge, and then either the asker or one of the lurkers actually ends up doing it (for all sorts of reasons). Not usually donating and QALYs, but very similar nonetheless.

It's as fun of a conversation topic for in-person conversations as it is on internet forums though. The results aren't very practical since they're all too far in the wrong direction, but I might be wrong about that since the process is definitely mind-expanding. I recommend this post on effective evil if you haven't read it already.
