So did Sadamoto Yoshiyuki make the cover of this doujin?
His name is listed on page 141 on contents.
It might not be impossible since some Gainax members provided some of their works on this doujin too.
Plus pages 136-139 seem like his work.
I would appreciate your help.

You can match the names easier by having this page as your guidance https://www.doujinshi.org/book/1710/Shin-Seiki-Evangelibon/ while looking at page 141 as it was posted already above.
Maybe we could tag more artists.
