Prefixes and typology

Hi, I've been lurking for a good while, but I wanted to mail over
something I've been working on. This is my first post too, so sorry if
i do or get something wrong. I've been working on my current language
since well before subscribing to the list, one thing that I've noticed
in typology is that in all the VSO or head initial languages that I've
seen, or that I think I've seen, all of them have some grammatical
alterations that occur in the first part of the word, like they use
more prefixes or lenition or similar. I wanted my current language to
be fairly typical of Head Initial ones, but I'm wondering if a
language that is almost exclusively prefix-favoring would be possible
or typical. I'm hoping to get some site up soon which'd deal with my
language and alot of other stuff that I have, I'll mention a link once
its done if wanted, and thanks in advance.
