Yeah 1000 words seems a good length, and it would be good to make up new plots or put twists on existing ones or something.
I think it could be fun to wing it so that no-one knows what you're going to write or where you're going with the chapter, but some ground rules could be laid down if you want like not killing off any character until everyone has had at least one chance to write them or something. And before it starts decide on where and when and with which characters the story will start?
