Yeah, it occurred to me that the possession might be nothing more than a plot device to get Loki into the story. If Jane is able to open portals from the beginning of the movie, Thor would not be forced to make a deal with Loki. But if she is temporarily incapacitated, Thor would have to ask Loki for help. So then Thor would have to choose to set aside Loki's punishment, perhaps putting people at risk in the future because Loki is out again without rehabilitation, in order to serve the cause at hand--protecting Asgard, etc. (a moral sacrifice)
In such a context, the possession would be a fairly minor plot detail that perhaps the studio would not mind being leaked. (especially if it keeps the fans distracted for a while
