There could be. However, it might not be as common as other crossovers. If you're into this very specific combination, you should also check Tumblr. Sometimes fans post snippets or links to their 'Harry Potter x Starbucks' fanfictions there. It could be interesting to see how authors blend the two universes. For example, they might have Hermione working part - time at a Starbucks in Diagon Alley.
One idea could be that Starbucks exists in the wizarding world. The baristas could be using magic to make drinks. For instance, instead of a normal coffee machine, they use wands to brew the perfect cup. And perhaps Voldemort has a strange obsession with Pumpkin Spice Lattes and the heroes have to use this knowledge against him.
In Harry Potter fanfiction, the Malfoys are often portrayed in a more complex and sometimes positive light. Some fanfictions might explore Draco Malfoy's struggle between his family's beliefs and his own emerging sense of right and wrong. He could be shown as having a change of heart, perhaps influenced by his interactions with Harry and his friends. This gives a new dimension to his character that we don't fully see in the original books.
In Harry Potter fanfiction, the exploration of good and evil can be really interesting.

Yes, there are quite a few interesting 'Harry Potter is a Slythindor' fanfictions. Some explore how Harry's character would develop differently in Slytherin.
