Though there might be several seemingly valid scientific reasons as to why this might be a great idea, my general understanding is that the likelyhood of it improving your instrument is exactly the same as the likelyhood that it might make it worse. There's an extensive explanation of cryogenic freezing of brass instruments somewhere in the TubaEuph FAQ, as well as a link to the results and analysies of several trumpet players who've had it done.
Basically, the results of cryogenic freezing are 100% subjective... for $50 I might try it. For the prices I've seen it charged at, though, I'd rather buy a dozen new mouthpieces. Besides, what on earth could possibly want to change in a 52j?!
Anyways, sorry I can't offer any first hand experience, but if you do end up getting it done to your horn, I'd love to hear about the results.
