Treat her less like a hot goddess, but more like your bratty sister, who needs to be taken down a peg. Gently chide her the way you would your sis (e.g., as Johnny Storm told Sue Storm in the Fantastic Four movie, "you don't look entirely ridiculous in that dress"). This conditions you to think of her in less intimidating terms, "with human breath, a traveler between life and death" in Wordsworth's terms, and not as a perfect "phantom of delight."
Turn yourself into the catch, not her. Have somebody else introduce yourself to her, preferably a woman. This gives her social proof you are okay, since another girl talked you up. Wear nice shoes, talk slowly to her (your variation of the Barry White bedroom voice), to make the best impression.
And think of it, her stunning looks are probably going to fade in 10 years, as added weight, stress and kids take their toll on her. Keep that in mind when you are tempted to get lost in the infatuation of 'eternal bliss' with her.
When you start thinking like me, getting girls will be the last of your worries. ;D
