In Ayreon's Into the Electric Castle scifi metal opera, Sharon den Adel's character thought the sun was a doorway and ended up dying a horrifying death just like the Denevan pilot from Operation: Annihilate. Worse yet, her death was accompanied by the hideous grunting of George Oosthoek. And we all know that playing jet ski inside stars ends up with cogenitors committing suicides. Not pleasant at all. Using the sun as a doorway seems like a very bad idea.
