It is, though there's a post among the Kyonko tags that shows the name written as "Suzumiya Haruhiko", whereas the Shumi no Heya doujin refers to genderswap Haruhi as "Haruki"
Imho, it is too soon to start tagging genderswap Haruhi as either "Haruhiko" or "Haruki", at least until they settle down for one name
KyonXKyonko doesn't seem too strange to me though, in all honesty , if I could make a clone of myself and genderswap it, it'd probably turn out to be my perfect girl =X
