"Wanna go, Prettyboy?"
Using the money from expiring UFAs Kane, Maatta, Petry, Husso, and by dumping / buying out two or three of Copp Holl Chiarot, there should be money on Detroit for Draisaitl next summer, if they're willing to go with Cossa and somebody cheap-ish for goaltending. It would probably push Compher to the wing, and one of Kasper Danielson would probably end up on the wing eventually or traded eventually, but that's all stuff that's worth dealing with if you can add Draisaitl for only cap space and without trading anything away to get him.
If Draisaitl were to leave Edmonton - and I don't think he will, personally - it seems very unlikely that he would go to a team that has to gut their roster and cheap out on their goaltending to make him fit.
If the Red Wings are going with Cossa and "something cheap" in net, I think that would make them pretty unattractive to Draisaitl.
