Yes..I do. I think if they rebooted the books and said that any new book really 'mattered' they would sale more..
No, they wouldn't. I think you've got the cause and effect backward there. The reason books
can't be treated as equal in status to canonical material is
because they don't sell more. Only 1-2 percent of the film or TV audience reads the books. Even if you quadrupled that, the vast majority of the audience for screen Trek would have no idea what was going on in the books.
Sure, there's a faction of fandom that says "I won't read anything that isn't cannnnnnon," but that's just a faction, no more representative of the buying public as a whole than any other faction of fandom, and they're probably just using canon as an excuse for their reluctance to read in general.
Besides, why do you keep assuming the books would
need to be rebooted in order to be compatible with canon? All Trek novels are
required going in to be consistent with existing screen canon. The only cases where they aren't consistent are those where an episode or film contradicted a book
after it came out (or, in some cases in the past, where a significant continuity error slipped through, but that's rarer these days). Most of the books published in the past decade are still compatible with canon, even when they aren't compatible with each other.
