Yup, good deal.

This pool essentially has two categories for goals (with GWG), so having a couple young snipers is great. I'd make the trade.

Value and situation-wise the deal is a good one.

Depending on the league and it's managers, dealing to strengthen a recent champion could be considered a dangerous move. Now it's not like you're giving up Stamkos/Ovechkin for bits/pieces and seriously tilting the competitive balance of the league - but always remember that any fantasy trade should put you in a position to win either now or in the future.

I'd always be inclined to refuse to help the championship teams, unless they overpay (even a little).
