Possibly using two layers of sheetrock?

I am contemplating using two layers of 1/2" sheetrock on a wall that is being re-covered (had built-in closets that are being torn out). As the old material was a sheetrock lathe and then plaster, it was quite thick. In order to make the total wall thickness similar to the previous, and to possibly increase sound deadening, I'm wondering about using two layers of 1/2" instead of a single 5/8" (I do like thick wall coverings!). My main concern is at the side seams. The two layers would both be laid horizontally (12' lengths will get the whole wall). Is there anything I need to do to the first layer at the seams to deal with the tapering on the edges or can I just put on the second layer using longer screws.

The other alternative is I could possibly cut one of the 12 footers in half length-wise so that, start with a half-width on the bottom, then a full sheet and then finish with the other half on top. The next layer would be two full sheets over that. Hopefully I explained that clearly enough.

Am I asking for trouble in any of this? Not concerned about the additional time and expense, just that it will be durable in the end.

I've only painted a few houses where they double laminated the drywall [when built]. When you do that you want to stagger the joints. Often that is easiest to achieve by hanging the 1st layer of drywall vertically and the 2nd horizontally.
