They already did and grew bored decades ago. this new Resurgence of Ranma fanart after Netflix brought the series back is still new and tame. Give them time to get back into pairing Ranma with Genma, Soun, Happosai, Ryouga, Ryu, etc....

Honestly, the Dojinshi scene is always Ranko/males. Girl-side Ranma is constantly getting fucked until she gives up being a boy forever. It's the thing.
