Eh...this is something I'd like to see, while not being entirely certain of being able to pull it off myself. Basically...
After having acquired max social links...Minato is dead. A series of short pieces from the perspectives of the people he'd come to know, both as they discover his death, and as they visit his gravestone.
The Fool Arcana and the Judgment Arcana are both SEES, and Priestess, Empress, and Lovers are Fuuka, Mitsuru, and Yukari, so...they would have been there on the rooftop. Unless you expand this to have taken place after FES, which I haven't played yet, in which case it would be after they'd all realized that they couldn't bring back Minato...and throw in Aeon for Aegis.
The Magician, Emperor, Justice, Chariot, Strength, Fortune, and Moon Arcana...or Kenji, Hidetoshi, Chihiro, Kazushi, Yuko, Keisuke, and Nozomi all attend your school, so...I would imagine that they would all find out at about the same time. And, of course, the Hermit social link, or 'Maya', is your composition teacher...though, this would preferably be after whatever thing I've heard happens in FES regarding her finding out that you were 'Tatsuya'...
The Hierophant Arcana and the Devil Arcana, or Bunkichi and Mitsuko, along with President Tanaka might not hear about it for quite some time...after all, Bunkichi and Mitsuko might well think you're busy doing something else, hence you not visiting...and President Tanaka cut off ties on his own. Hence, unless they notice you in the obituaries, or someone mentions it to them...it could be a bit.
The Hanged Man, Temperance, Tower, and Star Arcana, or Maiko, Bebe, Mutatsu, Mamoru all, as I recall, all moved or left...Maiko to live with her mother, Bebe to go to France to try and convince his relative to allow him to come back, Mutatsu in order to track down his estranged son, and Mamoru for his new job. Hence, they probably wouldn't find out for quite some time...but, on the other hand, Maiko and Bebe both have compelling reasons to want to check up on you later, since Maiko wants to marry you, and Bebe considers you to be a really close friend. Mamoru would probably also want to eventually get in touch with you again, I'd imagine, and Mutatsu would probably want to check in with you once he tracked down his family and made up with them...
The Death and Sun Arcana, ie, Pharos/Ryoji and Akinari...would definitely be the oddball ones. Ryoji is part of Nyx, and thus sealed away...but there could certainly be a section with him perhaps regaining consciousness for a bit, or at least whatever small part of Ryoji that is inside Nyx, and his thoughts on Minato and his sacrifice. Akinari is...well, at the end, a ghost. So...I think there could be something done with that, perhaps his spirit visiting the seal at some time, or just even haunting his grave, knowing more than most of what had really happened to you...
Tears shed, reflections on what Minato meant to each of these people, memories, and perhaps even their reactions to each other...to a certain extent. Though, I'd, uh, personally prefer to avoid catfights, given that you would have become pretty close to Yukari, Mitsuru, Fuuka, Chiziro, and Yuko...
Well, just a thought, and I still have some social links of my own to complete (Priestess, Empress, Moon), and FES to play (see the epilogues and Aeon)...but, well, it's something I'd like to see, sometime. Not something humorous, just...people coming to terms in their own different ways.
Thoughts? :mellow:
