Meeting by destiny

Why: This is a totally random idea that popped into my mind, and I have no idea whatsoever how anything like this could be carried out, but it would be very, very cool if it could be done. What if...when Obi-Wan finishes watching Leia's hologram and realizes who she is, we hear him say "Funny how destiny works." This would work perfectly because instead of him seeking her out or telling Luke about her, destiny brings them together. There is already a brief moment of silence after the hologram before Obi-Wan says to Luke, "You must learn the ways of the Force if you are to come with me to Alderaan," and it could be put there...but how to do it, that's the real question.
