I'm not sure if it's just here in Australia, or a worldwide movement but it seems non-traditional are more common than not. 2 of my sister's 3 kids have names she made up. The only problem I foresee with these kinds of names is pronunciation. I actually like your choice in names as they're easy to pronounce, speak a bit about the parents/family but not so unique that folk will be confused when they say their names.
Just some advice though from a guy that had his first kid yesterday. Your name will probably change when it comes time to apply them. It's a fun game when it's fantasy (like winning the lotto) but we found that when it was crunch time .. our tastes, names, etc changed a lot.
