Is there a way to use constructive interference to create a specific sound in a specific location?
Not in any practical sense, no.

Constructive/destructive interference can only change the amplitude at a given frequency; it cannot produce a frequency shift. Combining multiple ultrasonic signals will only give you another ultrasonic signal; it will never result in an audible frequency.

Audio "dead spots" are the result of multiple audio paths that happen to perfectly cancel out at that spot. They are, in a sense, "unstable", because the balance is only hit at that one exact location (and, in most cases, even then only at specific frequencies). At most other locations, the sound can be heard normally.

There's no way to get the opposite effect you're describing, of a set of signals that cancel out everywhere except one location. This is because there's no way to make signals cancel out everywhere, besides making them perfectly equal and opposite, and originating from the same point. (At which point, there's effectively no signal being transmitted at all.)

What is possible is to produce a single point of constructive interference, where a sound is perceived louder than it is elsewhere -- this is simply the opposite of the "dead spot" effect I described earlier. However, this doesn't translate to the effect you're describing: the sound is not re-emitted from that location; it can only be heard by a listener in that location, and they will hear it coming from all of its "real" sources.
