There is a way to reduce current. Take a look at the Current Hack on IC, only hack the current in the opposite direction. I believe the discussion starts at post 320 but you can probably contact Peter Perkins directly for more info.

As for the packs, they're all likely not long in this world, but you may be able to build one marginally working pack from three toast ones, and get another year or two out of it. Although it's not the "right" way to assemble a pack, I'd say charge them all to full, let them sit a month, and do your best to match cells by voltage. The more outliers you can get rid of, the better.
