Keep in mind, light (from its perspective) has no speed.
It only appears to travel at c from the viewpoint of an observer in the same reference frame. The photon, from its perspective, is emitted and arrives at it's destination, no matter how distant, instantly. No time elapses. This is why going faster than C is such an incredibly difficult problem, and why physicists will tell you an FTL drive would be like inventing a time machine. C, in our universe, is literally the propagation speed of cause and effect itself. For you to personally go faster than c would mean getting somewhere faster than instantly. You'd have to get there before you left.
You have to figure out how to break some pretty fundamental rules of our universe to go faster than c or enter some state not governed by spacetime (hyperspace? Fold Space? There are as many ideas as there are sci-fi writers), and if you change the definition of c you change how cause and effect itself works. Things get really, really wonky then.
It would be better if it were just... magic.
