IMO the only teams that would be interested in Gibson at the TDL are two teams - Carolina and Edmonton - who have legitimate SC aspirations and feel that a goalie upgrade is their missing piece. Verbeek holds all the cards in that trade negotiation and he should drive as hard a deal as possible and get his price. If the price isn't met then Gibson stays.
The summer is another matter but that is too far away to predict who will do what. Gibson would be smart to just continue being a good soldier and play well. If he really wants out that's his best way to get out.
