I guess it depends on how Hyperspace works, and if you can change direction without falling back to sublight speed. I imagine that Luke got to the Jedi sanctuary by going from planet to planet and studying the age of any ruins, searching for clues, and so forth. Anyone who followed this path would have to fall back to real space any time they encountered a planet and calculate the next jump even if they knew the ultimate destination, since there would be a planetary mass directly in the way of this route. Any deviation from this precise path and they might fly right through a star, or bounce too close to a supernova and that would end their trip real quick wouldn’t it? 😉

I’ll probably never have enough material to implement the change anyway.
