I understand this is unrealistic but I think IF it were possible these would be good solutions.
I added Kempe onto the second line because Mittsy needs a goal scorer on his line.
Dvorak simply for faceoff help.
Leddy for extra 1mil of cap space and still has the speed.
Mcleod for speed and a definite fourth line center.
Guhle for a third line left d-man who has speed.
Saros because.
