Personally i'd be happy with just slowing down the inertia of fleets in hyperspace to actually feel like another 'space' and not just a 'normal space' superimposed upon another one. Hyperspace needs some gameplay impact aside from fuel use and space contraction. Sluggier fleet movements on the 'world map' would go towards that, as would gravitational pull from nearby wells, as Dayshine mentioned or some weird effects that paint another layer on combat and maybe gives rise to 'hyperspace pirates' as a breed which tactics only work in hyperspace.
On that note, i don't know if the space between systems is 'mapped' and can actually be accessed with just moving one way for a long time, but if so, i'd like that when you run out of fuel you just drop into normal space from wherever you are and forced to 'walk' all the way back, with all the dangers that presents. (scuttling ships to conserve supply and such)
Since so far, fuel is given minimal afterthought. Worst case scenario, i just get dropped down near a planet in a system.
