I like it. It seems like you're covering most of your bases. I would start out the conversation with something from the text messages thread, build some rapport, and then use your strategy.
For example:
You - "I just got you to open your phone for no reason...looks like I got you in check

"
Her - blah blah blah
Then, you run your game. Make sure to remind her about the other night you met, what was talked about, etc. Girls like to have these emotions they felt with you brought back up. Then, go in for the kill with your text. Really solid, I'll give it a shot.
