I would be open to something like the following near the TDL:
Severson
Holtz
Horvat
We will need to free up a roster spot on D for L Hughes, and I am really not that high on Holtz. Horvat is a heavy player and gives us some really nice depth down the middle, allowing us to play either him or Mercer on the wing. It essentially gives us 2 very solid 2 way centers to shut down the opposition, and could free up Hischier to get easier matchups as well.
Vancouver gets a young shooter coming off a great rookie season in the AHL, and should also be able to flip Severson for a 1st at the TDL.
