I am wondering too what lines they come up with but this makes more sense to me:
Saad - Toews - Cat
Perlini - Strome - Kane
Fortin - Kampf - Kahun
Hayden - Kruger - Martinsen
Of course I think it is unlikely they will trade/scratch Arti immediately, so I seem him dropping to the third line and Kampf or Fortin to the forth. One of the problems with Kane's recent centers (Arti and Schmaltz) is they weren't very good at draws. Strome is apparently good at faceoffs. That solves one problem. Then you use Perlini as a poor man's Panarin and send Strome to the front of the net. I think for this trade to look good, Strome and Perlini have to be able to help Kane score at a decent clip and play responsible d thereby solving a second problem. It seems in the last year or so when the Hawks matched Arti with o talent his line bleeds goals, and when he is matched with defensibly responsible guys his line can't score. I think it is a misallocation of resources to replace any of the bottom six with Arti, so it seems Arti is the odd man out and should be traded.
One other point, Cat went cold when he was taken off the top line. I think it is too much pressure on the new guys to match them with Cat and hope that Cat and Strome recapture former glory. I say put Cat back on the top line, where he will be playing with a rejuvenated top talent who has had success with him.
