Swedish election 2010

Is there any concern on the Alliance part that they could lose the election merely because the Center and Christian Democrats both just miss the 4% threshold?  Say support for the moderates grows, but grows too much so that the other parties are just weakened enough to win about 7% of the vote combined, but no seats.  Have any parties discussed lowering the threshold %?

Are the Swedish Democrats not considered a coalition partner merely because they support massive immigration reduction, or for other reasons? Or to ask the question in another way, if a mainstream party all of a sudden became supportive of far less immigration than the status quo, does that make them all of a sudden no longer potential participants in a coalition party?
