Always Potterheads

Canon!!

So... I came up with this whilst walking my dog. I seriously have some weird thinking issue where my brain has good ideas in the most random places!
But that's not important.
I came up with this canon, and I think it's pretty cool.

What if, Lily Luna had her father's eyes and her mother's hair and looks. That would make her almost identical to her Grandmother.
So then she starts Hogwarts, she gets sorted into Gryffindor. She is bright and kind making her a lot like Lily Potter.
And one day, she finds a portrait in the dungeons on the way to potions. It is empty, which she finds odd as all the other portraits people in them. So she calls 'hello, is someone there' and Snape appears. For a moment he thought he saw Lily, but then realised it's not possible. She introduced herself seeing his confusion.
And from that they Lily Luna visited Snape's portrait every time on the way to potions saying things like "hello Professor" or "how are you Professor". And that, made Snape smile every time. Which is something he lacked after Lily Potter's death.

What do you guys think? Any good? Want more?
