My problem with this argument is not necessarily your side, but the premise of the whole argument in general. I view the appointment of the C to be a more organic thing. You're asking what we think would happen if someone else were captain, while I honestly think that could never be the case. Lidstrom is the Captain because of what he has done and who he as been for this team. Because of this, regardless of who has a C arbitrarily sewn to their jersey, you know which of the warriors the rest of the team will look up to when the game is on the line. Nick, alone, is the logical Captain of this team and will remain as such until he retires.
I don't know if I am making any sense or just blabbering nonsensically.
Although, I do feel the way that Babs seems to swoon about Nik in the press (and has pretty much ever since he got here) seems to indicate to me that Nik is doing an alright job as a leader inside the lockerroom, in addition to where we all know he is one of the best leaders in the game; on the ice.
