Dahlin, Mittelstadt, Thompson, Bogosian, Pilut for Nico Hischier, Taylor Hall, Wayne Simmonds, PK Subban, Miles Wood
Not sure if the salaries work out but you give the Devils a group of young players they can build around (along with whatever super high pick they will have this year while the Sabres get veterans that can step right in and a future star in Nico. I don't love the idea but it's something like what you asked for.
