As I wrote before, Kekkei Genkai are really overrated. With 6 years left until canon, Fujin would better focus on Fuinjutsu, Sage Mode, and creating unique Wind techniques similar to the Wind Chakra Armor and its advanced Vacuum Armor. P.S. Also don't forget that the fanfiction is called Calamity of the Wind. Are you seriously hoping for a different element?
I really want meiko to live through the uchiha slaughter maybe fujin will save her from itachi and she develops a crush on fujin. Plus having someone to teach sasuke there clan techniques vs how he was in canon would be way better for his growth then maybe have fujin teach naruto so they both grow stronger
In case you don’t want to just focus on ninjutsu. Some inspirations for wind-styles taijutsu could be found from the WEBTOON gosu, you could look at its wiki especially it’s divine heavenly destruction techniques or flying flash sword for sword techniques (They fit his theme since the divine techniques include vacuum techniques and the flying sword includes air slashes)
