I like this a lot. It's a really nice, elegant idea, and I'm generally in favor of any efforts to make less christmas tree-ing.

A couple things. It would be helpful to point out which properties apply to range weapons, which apply only to range weapons, and so on. Some are obvious, but some (for example, "Can be used to trip") aren't. There's also an issue of choosing damage type or the, "Additional damage type," property; this seems to be a property of ammunition, not of a bow/crossbow.
