I've meant to do this. If you want apple flavor you won't get very much using juice; look at your average hb cider, which is 100% AJ, and even there its a challenge to keep an apple character. However, if you use frozen apple juice concentrate, you can do a "gravity boost" that will deliver more apple flavor. I do this with ciders sometimes.
Which isn't to say that using juice is not without advantages...if you prefer a drier beer it should thin out your wort a bit, increasing the proportion of fermentable to unfermentable sugars. And if your grain bill is subtle enough I can see a pleasant fruitiness coming through...maybe not something that shouts "APPLE!", but I haven't done this specifically, so I could be wrong. I have done malted ciders which is sort of the reverse, but my primary experiment was a bit of a failure for other reasons.
And yes, bottling with a gallon of juice in the bottling bucket, prepare for bombardment dude! Yikes! Never had a bottle bomb but that sounds like a perfect recipe for one! Unless beerider was thinking measuring a quantity of juice to substitute for priming sugar, but then it'd be a lot less than a gallon and have just shy of no influence whatsoever on flavor (at least to my hardened, war torn taste buds).
EDIT: Also, forgot to add, I wouldn't add it during the boil, allegedly this will set the pectins and create haze issues. If its pasteurized (which I'd recommend) I would just add it to the primary fermentor after the wort has chilled, before pitching. EDIT #2: major, you said you've sparged with AJ...any noted effect on clarity to your recollection after the boil?
