I don't see how this will work considering the contraction of space-time right in front of the spaceship within this warp-bubble, will also in-turn cause a natural dilution of space-time right in front of the warp-bubble.

Even if that was not true, how will the warp-drive propagate the warp-bubble field itself faster than C to grab onto space-time in a timely manner?

It would seem to me this would cause the space-ship to feel that it's traveling faster than C, but to an outside observer it would only be traveling at C or less.
