Yeah, go ahead and try that. I dare you.
If those batteries are hooked together for more than a few seconds there will be smoke and melting of the insulation on the cables. Believe me, I've seen it.

You're thinking of hooking a good and dead battery together of the same voltage. That may have some of the charging effect you describe. But, you can't charge a dead 6 volt battery with a good 12 volt battery. No cable will handle the current and neither will the batteries.
