Sadly, Clark and Bruce would have to be the same age for me, so no "senpai-noticed-me" moments between them in that way! But that doesn't mean there couldn't be a lot of blushing and stammering and "I don't like you, baka!" scenes. ^-^ I would imagine Clark and Bruce would be the cool upperclassmen everyone has a crush on, and everyone thinks they're totally tough and suave and with-it...but secretly Clark is a huge dork who's into some obscure television show and doesn't want everyone to know he's actually an otaku, and Bruce is secretly super-shy and has cultivated his aloof persona to cover that up. So the more "Batman" and "Superman" side of them is actually the public face in this AU, and the "Bruce" and "Clark" sides become the secret that they're hiding.
Maybe Bruce comes across Clark in Akihabara fanboying over his show and Clark is certain that Bruce is going to make fun of him, but Bruce says "If I don't tell anyone you're into this stupid show that I certainly don't know anything about, will you help me work on this speech I have to give at graduation, not that I have a terrible fear of public speaking or anything, baka.." And at some point while Clark is tutoring him (of course) he talks about his beloved show and Bruce slips up and reveals he's just as crazy about it as Clark is. :)
Annnnd, the Robins are totally underclassmen who worship Bruce and he's terrified of losing their esteem, and over the course of the story they come to realize he's not perfect and they do stop worshiping him so much, but Bruce-senpai also comes to realize that he'd rather they know him as a real person than idolize a facade, and probably at his big graduation speech he "comes out" as a fan of the dorky show Clark loves, and maybe comes out in other ways as well, and Clark blushes furiously in the audience and they decide to go into business together (making manga? running a fanzine?) and the end of the story is an image of the two of them on the cover of a magazine as "Japan's New Power Couple" with their arms around each other.
(I was not sure I could come up with something for this, but it ran away with me anyway!)
