Take out Kane and hawks might accept

Maybe not even.

Kane and Toews are not exactly best buds so the chance of them saying, they will only waive together to the same team, has less then 1% probability.

Are they not? I haven’t read anything suggesting that, and they used to room together on the road for years.

“Hawks fans” might not accept. But Hawks fans might also want to start preparing to get absolutely fleeced when these players dictate a trade for a bag of pucks to wherever they want to play, or refuse a trade and walk for nothing.
Toews likely costs the Hawks to unload for any cap hit at all at this point. Kane could fetch a Giroux return: a floundering prospect and a 1st 3 or 4 years from now if bundled with other C tier prospects.

Kane is a lot better than giroux. Toews' play this season will ultimately determine his value. He was starting to look like himself towards the end of last season. They're both extremely loyal players. Can't see them screwing over the team by only giving 1 trade destination. And there's zero chance the hawks take your insult of an offer. Toews and Kane want to go to a contender. Not a retirement home that the Pens are for the next 4 years.

They are not. They don't spend much time together off the ice at all, and haven't room together in a decade
