Shouldn't matter at all. Wart is dunesfolk on paper, but I made him plainsfolk in the creator for the sideburns option. I refuse to believe only one clan of lalafell can grow hair on the sides of their faces. Other than that, he has tan skin, light colored hair, and he hangs out in Ul'dah. Unless someone is studying the character creator options, they'd just assume he's dunesfolk. If you're just going keeper for the eyes and keeping the rest looking very seeker-esque, no one will notice or care that you're a keeper. You can still RP your character as a seeker without issue.
