If you're willing to do wigs, you could look into Seras from HellSing Ultimate. She has shortish blonde hair & blue eyes but the description of your body type would work well. Plus, if you like military weapons she tends to carry badass guns XD.
Oh my gosh Seras, I remember her. That'd be soooo cool!
