My Scherzer deal with the Yankees would basically be:
Clint Frazier, Estevan Florial (#1 prospect), Thairo Estrada, Anthony Seigler (2018 1st round pick - catcher in low-A; #7 prospect), Clarke Schmidt (2017 1st round pick - SP, #6 prospect) & Domingo German (SP), to start. That's probably pretty light, honestly. I'd also ask for Chad Green and probably Greg Bird as a throw-in reclamation project.
Hard pass on Severino. I love the kid but shoulder issues are absolute no-gos for me.
