Hehehehe, Star Wars hyperspace. Love it.
Yes, it would be cool if inhibitors interrupted jumps. However, not the current kind of jumps. My thoughts would be to make the JD an actual "jump" drive that maintains functionality.
The best way to "jump" from point-to-point in real life would be to bend space and time and move from Point A to Point B via Point C, where Point C is a fold in space and time. This fold allows you to move from one end of space to the other, almost instantly. The problem, of course, is that you have to fold space and time. Space and time take a LOT of energy to fold. So this system should require a lot of energy (As in, capital-ship-grade energy storage) but be capable of moving a ship just like it does now. This would make it a tactical weapon rather than a really limited form of travel.
That said, hyperspace should be a dimension/place/method of travel in which you move fast and (At the risk of turning this into Star Wars Episode 6 1/2: The Block-based Expanded Universe) can be affected by large objects (And only be large objects) in real space. In other words, if you fly through a star in hyperspace, you die. So fly around. It's safer that way.
This would also make exploration tough (And consequently make exploration-based bonuses more balanced) because if you try to hyperspace out to the furthest reaches of the galaxy, you'll probably hit something on the way out (Because you shouldn't know where stars and/or planets ARE yet) and die a horrible, expensive death.
