Josh Haber confirmed that Luster is Starlight and Sunburst's daughter. Although, Jim Miller doesn't like the idea since he thinks it makes MLP feel too small with not introducing new unrelated characters, and that he felt it was a plot hole with Luster not knowing that Twilight was still friends with the others (but if they only meet once a month, she could still assume that, so it's not really a plot hole), and that he would rather leave it up to the fans to decide. So that's a maybe/up to fans from Jim and a yes from Josh. Still, even a single confirmation is enough.
