I agree with you and was somewhat disappointed myself when I did not find the magic instructions to how to trap one cat out of a lot of them. There are all those untrappable cat ideas like using a large fishing net, but that would never work for Luna and would probably end all your efforts, not to mention that you need to be pretty experienced with that kind of thing. I own a drop trap that I can't use as I never got the hang of transferring the cat and my only attempt resulted in the cat simply butting his way out of it. However, one of my own pets, Eliot, loved it and thought it was a laff riot when I brought it inside to practice. Sat under it over and over again.
Approaching Luna is probably not a good idea unless you start to see her so often that she begins to remember (not saying that she forgot) that she can trust you in her new environment. The flyers are a good idea and while it might take time, if you can coordinate the feeders eventually that would be excellent. There is a lot of legwork here but it seems as if there is now a plan of action since the sighting of her a couple of days ago...so you are moving ahead.
In your general area that you have discussed, how many cats are there more or less, fixed or unfixed?
I don't know if contacting Alley Cat Allies Feral Friends Network would help. They put you in contact with volunteer TNR people who do a lot of trapping. I have to say that I have never received any help from them, including advice, but you might find someone who might have some ideas for specifically trapping a hard to separate cat. All you really want is advice, so it is pretty quick to just register with them and see if anyone answers.
