Anybody else think Heavenly Host Elementary/Tenjin Elementary should be a large-sized stage (like Melee's Hyrule Castle) rather than small-sized as it appears to be in this image?
I think it should cover a full cross-section of the school, with the outdoor pool on the far left, the second building with the music room and principal's room on the far right (with the walkway leading to it), the spine-chilling girls' bathroom on the top floor and the bomb shelter at the bottom. Perhaps the stage hazard would be that it randomly has an 'earthquake' and the layout of the platforms change, sometimes even removing entire sections such as the second building.
Of course the bgm should be this:

In terms of playable characters from Corpse Party, the obvious choices would be Shinozaki Sachiko, Mochida Satoshi, Shinozaki Ayumi or Kishinuma Yoshiki. However I think Yoshikazu is more appropriate for a smash-styled brawler, he'd probably be a heavy character, not unlike Ike. He'd probably also summon the four children for specials:
Standing B: Tokiko, short range burst that knocks characters away.
Forward B: Yuki, she runs out to stab the opponent in the eye.
Down B: Ryou, he sits in the place where he's summoned facing the same direction as Yoshikazu for about 5-10sec or until a character faces him, at which point they are 'trapped by his gaze' and paralysed for a few seconds.
Up B: I can't think of anything. And Sachiko would probably be a playable character anyway.

Damn I've come up with way too much.

All of my yes, that is exactly how I imagined the stage would be.

https://www.youtube.com/watch?v=-ZZZUJpEd-Q also works, I think. Of course, there's always the ever-popular Chapter 1 theme.

Actually, I think Ayumi is the most suitable candidate (Remember, even characters who have no chance in canon [Olimar for example] can fight on pretty-much equal ground with every other veteran fighters). This is partly because she plays one of the biggest role within Corpse Party and is also the most popular character in the Japanese community.

He'd probably also summon the four children for specials: 
Standing B: Tokiko, short range burst that knocks characters away. 
Forward B: Yuki, she runs out to stab the opponent in the eye. 
Down B: Ryou, he sits in the place where he's summoned facing the same direction as Yoshikazu for about 5-10sec or until a character faces him, at which point they are 'trapped by his gaze' and paralysed for a few seconds.

Once again, this moveset would suit Ayumi more, as it is shown that Ayumi has strong affinity with the supernature, so it would make sense that she can summon them. And there is also Ayumi's infamous "Darkening" as the Final Smash! :3
