It could be argued, that there are many different ways to accomplish something, if you have enough intelligence, energy and a sufficiently advanced industrial base. And if all else fails, there is always the brute force approach.
If we exist for long enough to develop all that, even things that might be seen as impossible could be done, probably by circumventing the obstacles. I can think of a few obsure ways in which we could transport ourselves through the galaxy and arrive much faster at the destination than a photon would take to do the same, that don't demand faster than light travel.
A really intersting way would be, that if time is quantized after all, and there is some "bookkeeping" done in the background that simplifies things to objects, it might be possible to trick the universe into thinking that some of those objects are at a different place than they were a moment before. In other words: teleportation.
But that would only work if the universe accounts with objects and not only individual particles. Otherwise, uncertanty being what it is, you could not have all the particles keep their relative distance and composition to one another, and the result would be very messy.
