Well, it is illegal depending on the context. Sometimes, producers like to change their age like making Miku younger, Rin older, etc. In one of hitoshizukuxyama's song (feathers across the season), they portrayed Rin and Len as non-siblings and adults in a romantic relationship and that's perfectly fine. However, in syncronicity, they're twins so that's not fine. If Yuki and Kiyoteru had a duet where they're represented as non-siblings and adults (well late teenage years is ok too) that would be fine but canonly, it's just no.
