Just make a backup of the book and try it. Then, you can decide if it is worthwhile doing for other books.

Here is my prediction:

- It isn't going to reduce the space used enough to be worthwhile.
- When reading it on the ereader, you will keep picking up the tablet and looking at the pictures in colour. While doing that, you read the next bit and look at the pictures. You won't go back to the ereader to read any more of the book.
