Lag Ba-Omer which Falls on Motza'ei Shabbat

When Lag Ba-Omer Falls on Motza'ei Shabbat, some authorities rule that the bonfires should be started later in the night to avoid the desecration of Shabbat by myriads of Jews (including the police), especially at the grave of the Rashbi on Meiron. The custom of the Admor of Boyan, who lights the main bonfire at Meiron, is to light after midnight.
In Shut Sha'arei Tzion (#14), Ha-Rav Shmuel Rabinowitz - Rav of the Kotel and Holy Places in Israel - discusses the question of celebrating at Kever Rashbi on Meiron. He brings a letter from Ha-Rav Zalman Nechmiah Goldberg (Rav Shlomo Zalman Auerbach's son-in-law) which says that the bonfires should be lit on Sunday during the day.
The Chief Rabbis of Israel, Ha-Rav Shlomo Amar and Ha-Rav Yonah Metzger, have suggested postponing the bonfires until Motza'ei Lag Ba-Omer. This is also the ruling of Ha-Rav Ovadiah Yosef. And this is indeed proper, since lighting a bonfire is not a Torah Miztvah and not a Rabbinic Mitzvah and not even a Minhag which must be observed. It is a non-obligatory custom (see the words of Ha-Rav Joseph Soloveitchik in "Mi-Pineni Ha-Rav,” pp. 218-220), and many Torah scholars do not even light a bonfire at all. After all, blowing the Shofar and taking the Lulav, which are Torah Mitzvot, are not performed when their respective holidays fall on Shabbat, on account of a concern that some individuals will violate Shabbat. And the State of Israel postpones Yom Ha-Zikaron and Yom Ha-Atzamaut to prevent Shabbat desecration. It is all the more so appropriate that the bonfires be postponed until Motza'ei Lag Ba-Omer when it is known that many people will desecrate Shabbat if it is not postponed.
Perhaps you will say that if we postpone Lag Ba-Omer then it will not be Lag Ba-Omer but LAD Ba-Omer (the 34th of the Omer and not the 33rd)? This is not a problem: the fact is that when Tishba Be-Av (the 9th of Av) falls on Shabbat, it is postponed until the 10th of Av.
Our Rabbi – Ha-Rav Tzvi Yehudah Kook - emphasized that a year in which Yom Ha-Atzmaut is moved to avoid Shabbat violation is a great sanctification of Hashem's Name, since this is proof that the Jewish State is preventing the desecration of Shabbat. The same applies to Lag Ba-Omer.
And to be sure, the Rashbi himself is greatly distressed by this Shabbat desecration, which is supposedly performed in his honor.
