No.
The Canucks need a top pairing two-way defensive-minded RD that can play with Hughes, to the point that this pairing can push the OEL-Myers pairing to an ideal 2nd pairing (OEL is a #3 defenseman while Myers is a #4 defensemen. Check that - OEL is a #2.5 defenseman while Myers is a #4.5 defenseman).
If the Canucks have OEL-Myers in that 2nd pairing slot, I think they'll be in tremendous shape. With Bear, Schenn, or Dermott as Hughes' partner however, you'd have to deploy this pairing in the 2nd pairing spot which would still keep OEL-Myers as top pairing (which would ultimately lead to significant risk).
When I created this initial post, I argued that acquiring a "sexy piece" such as Zub or Severson sounds great in theory, but the acquisition cost would be quite high. The Lundquist trade only confirms my suspicion. Cal Foote from Tampa? Would probably be an insane price as well.
