the knowledge book is hardcoded. you're able to rearrange the 16 slots, but you can not add functional ones.
you could remove some though to get a set of slots per page that's divisable by three, but those spells put in the "hidden" slots won't be accessable anymore.
hmm... what could be done is the following: a resizeable knowledge book with the standard 4x4 arrangement. move the spells from the last row to some other slots and then resize the window to get a 4x3 arrangement.
