The first question to ask is what we should do on her ideal Caribbean vacation: sit on a beach reading, explore quaint villages, shop, hike through rain forests, sail, snork...? Pretty much anything can be had in a place where you can do two or three tanks a day of great diving.
Unless she is really into sitting on a boat deck and reading, I can't see how a liveaboard trip would be fair to her. At minimum, you'll be leaving her on her own for 3 or 4 hours a day, so I'd make sure there are plenty of activities she likes so the time will pass quickly.
Have you thought about separate vacations for that week? There might be somewhere she wants to go that you'd just as soon skip.
