Twilight Sparkle x Songbird Serenade

[SkyPie 259]

What do you think of this possible ship? I think it could be quite sweet and it gave me the idea to headcanon Twilight as bisexual, as well as having a celebrity crush on Songbird since she was a teen. In an AU I thought up, after the defeat of the Storm King and everything dies down, Songbird had grown to admire Twilight for being the big hero. She comes to visit Twilight to ask her to hang out. Their relationship grows from there.

By the way, can someone explain to me why Twilight and Songbird looked at each other twice like they were speaking without words? When I watched some clips to get screenshots, I think in the last screenshot above, Songbird did a downward motion like she was winking and Twilight nodded in response. I don't get it.
