Well, aside from Val trying to invent psychohistory (DO NOT FOR THE LOVE OF GOD LET HER DO THIS) the supergeniuses could probably be persuaded to come up with some trivial quality-of-life enhancing stuff. Like, I don't know, an algorithm for the City stoplights that cuts down on traffic, or other things that are improvements on existing tech that wouldn't be giving Vulcanus an advantage if they got their hands on it.
