What a great idea. With my great respect for Rav Adin and fond memories of our work together in the FSU I'd love to contribute. Since starting Daf Yomi in 2012 I've been keeping a journal of sugyot that interested me. I'll try to choose a few that I think might belong in your anthology.

Brachot 8b. לוחות ושברי לוחות ×ž×•× ×—×•×ª ב×רון

Shabbat 31. The stories about Hillel and Shammai. זיל גמור

Shabbat 75a. A sugya on what we can learn from the Persians. Permissible, even obligatory assimilation.
Shabbat 88 and 89 a and b. Amazing agada. Including × ×¢×©×” ×•× ×©×ž×¢ vs. הר כגיגית
Shabbat 104a. מ××™ ×˜×¢×ž× ×©×§×¨ מקרבן מיליה, ×מת ×ž×¨×—×§× ×ž×™×œ×™×”?
That's a sample from two tractates. I'm rushed today, but if you want more, I can probably find time in December.
