Would definitely be cool. Once each person finishes they could complete a single model like the mini exchange to send to the next person who is finished.

I created a (now stickied) post for 6 month and 1 month goals.

The idea was that the winner has to come up with something for the next winner. Anything from a pile of bitz to a full squad. It depends on what you have and want to give away. Even if I made a whole squad for the first winner and only got a snotling if I won later, I wouldn't care. It's only to encourage people to reach their goals.
