I'd go for broke. If you haven't posted it on LJ already, post the whole thing here because--unless you have it up on a site--no one will be able to access it. If you've already posted it on LJ maybe having a post with a link to all your previous posted chapters would be a good idea? (I'm not a mod here so don't quote me.)

Although I would suggest combining some of your chapters into one because they are fairly short. That might help your feelings of 'swamping' the site.

BTW, if you're interested I have concrit on your work. I like the complete absence of weirdness v. much.
