What if Lilo and Stitch was a book series?

Lilo and Stitch is considered one of Disney's best films in the 2000s, spawning sequels and a few TV shows. But what if it was a book series before a movie?

Changes

 * Lilo and Stitch would have been a book series created by Roald Dahl from 1968 to 1986.
 * [have Disney buy the rights to the books when they were producing the movie?]

Books

 * /Lilo and Stitch/ (1968) - TBD
 * Lilo and Stitch: [based on Stitch Got a Glitch or Hammsterviel's introduction or kinda mix both together in some weird fun form]
