I don't have in mind the way the entire interdiction mini game could be expanded but it seems like the present interdiction could be considered the last part. The actual interdiction game could begin as soon as an NPC decides to interdict but Isn't right on your tail yet. The point of this part of the game is to lose the interdictor before you are flying through the final tunnel.
The first part might involve tunnels that branch into more tunnels. Which tunnels can be entered is determined by your super cruise speed. Some tunnels require faster speeds to enter but are also narrower requiring better piloting skills. Slower tunnels have greater turbulence meaning heavier ships have the advantage. Heavier ships create a supercruise wake meaning smaller ships have a harder time following their tunnel directly. Instead smaller ships have to gain ground by choosing faster tunnels.
There could be other characteristics of the tunnels making them better suited to different types of ships. These tunnels branch, intertwine, connect, split, reconnect, and when near objects in space some tunnels might veer toward them to emulate an idea, for example, of using a planet's gravitational well for some advantage, or to pass through the rings of a planet so as to emulate losing the pursuer in the asteroids.
Since the interdiction game would become longer, I propose that based on how fast the tunnels you traveled were, you always end the interdiction near your destination, if you have one, and how long the mini game is, is based on how far from the destination you are.
