Combat Hapkido (www.ichf.com) is a pretty good "add-on" system and covers just about anything you'd like.
I think if you're choosing between two such radically different possibilities, you need to give some thought to why you're looking for add ons. If you had a specific need in mind, you'd probably have no trouble determining which of those two suits your needs. And if you don't, perhaps now's not the time to add something. Just a thought.

Personally, I'd go with Judo. Reasons being (IMO) its different enough from nearly any TMA you'll do to compliement it well. Its also tremendous fun...
Fun? You said fun? Whoa now, hold on there missy. You can’t seriously be advocating doing something because it’s fun. Come on now, taking up a particular martial art because you actually like that martial art is preposterous! My goodness, what is this world coming to? ------ Oh, and, what Ap Oweyn said: Do you want to kick more or throw more? Both are good.
