Yup, that will work just fine. You do need to be sure you puncture ALL the cell pouches.

Just leaving them ripped open will kill the cells fairly quickly but if you toss the ripped open pack into...

Not quite.

In my tests the current that flowed through the salt water was pretty much in direct proportion to the size of the conductor that was immersed as well as the salt concentration.

Actually, Fred and I disagree on the final step to slit the packs and put them in salt water.
