However given that a recent and formerly impossible thing in hyperspace is now called the streak drive. One might find a much lower slower band that one can only enter for a few seconds. A quick jump something all other hyperdrives go right by. A micro jump that one bounces off of the lowest slowest band never quite getting there immediately forced back into n-space. Only appearing a few seconds later much further along than one otherwise would have been. given that it wouldn't get into the lowest band it might work inside the hyper limit. Might only work inside the hyperlimit.
Actually, the streak drive was not considered impossible. David actually told us early on that there was still research into reaching higher hyperbands. David put the rifle over the mantelpiece right from the beginning. So the streak drive was simply an extension of existing tech--in fact, it turns out not to be new tech, but simply a brute-force application of greater power with existing tech.
On the other hand, David has explicitly stated that transiting to and from normal space inside the hyper limit will not work. This is not at all the same situation as the streak drive, which David had explicitly set up as a possibility.
Perhaps you want to compare instead to the spider drive. But that comparison doesn't work either. David never said anything about whether an alternative drive to the impeller was possible. He didn't say it was possible, and he didn't say it was impossible. Unlike the streak drive, David did not put the rifle over the mantelpiece for the spider drive, and it came as a surprise. But it also doesn't break his established physics. A hyper transit inside the hyper limit breaks his established physics.
David is fairly careful about his physics. He doesn't always match it up correctly with real-world physics (much to the distress of us nit-picking physicists
). But once he establishes in-world physics, he will not break it unless necessary, and seldom without setting up in-world clues and explanations in advance. It is perfectly reasonable to speculate here about future breakthroughs based on possible clues or hints in the text or infodumps. But speculating about potential breakthroughs when there is no evidence at all, or specific evidence against, is pointless. If someone proposes time travel, what can anyone say in response that actually relates to the Honorverse except that there is no evidence to support it? If you propose the possibility of transiting inside the hyper-limit, what can anyone say that relates to the Honorverse except that David says it can't be done? Any further discussion is completely irrelevant to the Honorverse. At it's worst, this kind of speculation verges on fan-fic.
