First off, is your wife somewhat willing to do this with you? Generally, hypnosis works if the listener allows the hypnotist to take them into trance. If the subject knows or is even a little suspicious, the hypnosis will have almost no effect. Subliminals are different, but they are usually to add to the hypnosis. They usually convince someone to act a certain way, but its extremely hard to use them to implant a trigger.
I'd say the best file for you would be trigslave, by EMG. It turns the subject into the slave of the speaker until the subject is told to revert to normal. If you can really get her down enough, she would forget what happened as a slave.
If your wife is against this kind of thing, then your best chance would be to convince her otherwise. If you tell her to do something she's completely against even when she's in trance, she'll either snap out of it or ignore it completely.
Goodluck!
