Hmm, I like the idea to a certain degree. It is fitting to kind of end with Luke before all the Leia stuff happens, so that we can solely focus on here. But! The sad thing is that Obi-Wan’s mission is in its entirety all about protecting Luke - so the film starts with Luke, and ends with Luke, is symbollic and most likely the most fitting way for it to end.

Well the film would still start and end with Luke, just that the end is the binocular shot, showing that Obi-Wan is still keeping watch
