Editing the video is by far the easiest solution. I can edit some of the audio to match the PAL video instead if need be, but for reasons of compatibility and the potential confusion this could cause, it may not be the best choice to do so.

In my experience, it's difficult to insert a new section of audio and get the waveforms to line up seamlessly, even if you're copying from another part in the source material. I say cut the two frames of video, then cut that same amount of audio from the PAL soundtracks to match (which will be easy since the audio will change with the scene change and provide a nice break point). We're only talking about 1/12th of a second, and I'm all in favor of minimizing confusion. You'll still see Luke stand back up before the scene cuts. :)
