Thanks for violating site rules with the reddie.reddies are for factually incorrect advice. And my advice was not factually incorrect.
I didn't say you could be made legal sisters. I said if you were to adopt her or she to adopt you then you would not be sisters. Please learn to read...both the rules of the site and the answers you're given. I said, again, reading helps, that you would be sisters if your parents were to adopt her or her parents were to adopt you. And I didn't say it would be strange for that to happen, I said your parents or hers might take offense (because you left out the fact that your parents are deceased). I said it would be strange if you were to adopt her or she were to adopt you. Because if either of you were to adopt the other you would not be made legal sisters.
You didn't include the fact that your parents are dead in your original post. So if her parents are up for adopting you, then go for it.
And your original post didn't say you were asking if other people who had been friends for a long time also wanted to become siblings. You asked for more information on if it could be done.
