If there is any magic bullet, it'll be something biological evolution can't easily jump-to or stumble-upon. Otherwise I think it would have happened already, given the risks of sleep and the rewards of an expanded activity (or at least awareness) cycle.

Well it's not unheard of that some people won the genetic lottery and are more efficient at it, functioning normally with only 3, 4 hours of sleep every day. There's definitely room for improvement for those of us that need 8 or 9 lmao. Hell even reducing it to just 7 or 6 would be such a massive gain.

For "Short Sleeper Syndrome", it remains to be seen what the long-term tradeoffs are.

Kind of like how someone might excel at a specific test because of a lesser sense of pain, but that lack of feedback loop can be detrimental in the long run as they keep injury themselves without noticing.
