If the manga starts back up and states that Alluka is male, then there shouldn't be any problem with changing it to male since you'd have irrefutable evidence direct from the manga that no one could argue. But as it stands, there's way more evidence IN-TEXT that Alluka is a girl. The manga does state that Alluka is male. I know it also states that Alluka is female. Also, in the anime, it happened. One of the Japanese scans referred to Alluka as "son" of the Zoldycks.
