I think that someone with the right knowledge would be able to calculate if it is possible. It could be that two planets have a certain speed so that it would be impossible for them to line up. I don't know.
But I am also thinking that all the planets on one side could cause a powerful gravity reactoin on the sun. For all I know, all kinds of funny things could happen. Maybe even the combined forces would cause one or more of the outer ones to fly out into the milky way?
