Maybe, but keep in mind that the ASOIAF series, and by extension the Starks, only really became well-known with the advent of Game of Thrones, which started in 2011. Not that Kubo couldn't possibly have known about it when he introduced Starrk, but he gave almost all the Arrancar an animal motif in their powers, and in MASKED Kubo said Starrk's name came from Phillipe Starck. So I'd say it's very unlikely.
