In short, yes. Some things are more difficult, and aren't as natural for adaptation, but I beileve anything can be made into something with the right creative team. Not saying everything will always work, but you have to be optimistic. There are so many books, plays, musicals, movies, etc. that nobody thought could ever work. But all it took was the right creative team and viola!
Example: The musical theatre world had written off Pygmalion as unadaptable. The Lerner and Lowe took a crack and the reast is history.
