I remember this team, you had way too much tied up in goaltending... As you are losing Karlsson anyway, this isn't all that far off. However, this offer does not fit what your team needs.
I think you are blinded by your leaf-nation glasses. You are giving up arguably the best goalie in the world and the best defenceman in the world in exchange for $1.5M in cap savings. This will still leave you with cap issues, and you degraded your team. Looking at your signature (and admittedly do not have the abacus out) I would rather outright drop Lundqvist (and Ekholm) and solve you cap issues that way.
Talbot/Price/Niemi in a 2G league is good. Maybe find a another much cheaper goalie when onecomes available.
Also... I do what I can to keep 2/3 of JVR, Carter and Edler. You have a good team there
