By all means try it. TBQH i don't think it is going to work because she will be confused, but I'd love for you to prove me wrong. It kind of reminds me of myself at one point when I would think up a bunch of different scenarios. As you know the key is action. Try the things out and see what happens. It's key to get out there, fall on your face, and mix it up and develop the gift of gab with women.
SDL Train Game is an interesting sub niche of all of this stuff, who knows you might get very good at it. In fact you will, if you focus on it and demand continuous improvement. And the women you meet will be glad you did so, who may just be looking for some excitement in their daily lives.
Cut through the buzzkilling early chat and sweep her up in magic instead.
I love this mindset. This is perfect. I think that instead of verbally pretending you already know her, you need to nonverbally convince yourself and act towards her as though you already know her without verbally saying "how've you been" or whatever. The hug etc. would probably go down a lot better if you just went in with "hey" instead of "omg hey" as the "omg" would cross her wires and set the interaction off on a wobbly start. The name trade can come later in the interaction; when it comes at the outset it's an acknowledgement that you're strangers. Coming later, it becomes a simple formality.
