Oh, man--keep us posted on this! The other thing to consider is that that experience will still be subjective (the old "Is your blue my blue?" conundrum) , so the sensation of sight/sound for someone who's blind/deaf might just be something different than how we experience it--which is pretty darn fascinating in its own right!
Again, how such a person would describe those sensations--the language that person would use--will be important to consider--and the question then will be if you can "recognize" light or sound in those descriptions.
ps: Remember also that sound, at least, is vibration--it can be felt. Light in some ways is the same. I remember a news item from back a-ways where this guy who's blind was allowed into, like, the Louvre and permitted to touch the sculptures in order to "see" them. Do the other senses step up to the plate and pinch hit to some extent for the missing ones? I definitely think so.
