Dilemma: to message without/before matching on this new thing on Facebook?

The question is pretty simple but I want to give some context, so my question is a little more understandable and so you can see my reasoning behind my dilemma.

Facebook seems to have made a dating setting where it's basically like tinder, but on facebook. So I found this girl there. I read her description and I couldn't stop smiling and see myself in that description: her interests, sense of humor, her education, everything really, is just me to a T. And I know it is very possible that we don't match, but it sounds almost impossible, in a certain way. Do you think it would be absolutely inappropriate to message her before/without matching?

I know what the pros and cons of how I might come off if I do, but I also know what I would possibly be missing out on if I didn't.
