Kudos for coveting a good player. I want Skinner on the Blues, bad. But there is no realistic combination of players on your team that would move me to trade you Parayko.
The only player in the league who is conceivably able to fetch Parayko in any realistic trade is Leon Draisatl. Of course, I'm not the GM. But I'm reasonably certain the deal you presented here wouldn't do it for Doug Armstrong, either.
