This article is more about edge gluing panels than stacking them (if I'm getting your idea right). http://www.thewoodwhisperer.com/articles/avoiding-cupped-panels/ But this is just to illustrate how wood wants to cup when it's not quarter sawn.

I think I would either orient them with the grain alternating 90 degrees to each other (like plywood) or if the grain is all running in the same direction, alternate the direction of the cup with each board - first one up, next one down, next one up, and so forth. 

The most stable would be doing both - the grain is alternating 90 degrees and the cup direction is alternating up and down.

Versus making all the grain run in the same direction with the cup running in the same direction. This one would be the most prone to warping.

Hope this makes sense.

Turn  the grain where  every other  piece the grain direction matches.Cut pieces about !/8" oversize both  ways  to allow  for net cutting to finish size (1/32' left for sanding). You can make this sandwich as thick as you can work and get enough clamp pressure to make glue purge. Apply thin coat of adhesive to all surfaces except the ones that you don't  want  to stick. (Not trying  to be a smart azz, you can get  caught  up in the moment and make  a brick0 Don't  ask  me how  I know (;-D)
