Welcome to the forum, Fred!
I'm assuming that you bought that okra, or you would have used smaller jars, to begin with? Like the others, I definitely wouldn't re-process it, even in a water bath, which would probably be safe, since that's what is used in commercial pickles, but they would get soft. Good idea to find some friends to give some to, where you could eat some with them, too!
I have to find a good recipe for pickled okra, as I'm harvesting a generous amount of it. I just sliced, blanched, and froze 4 pints of it today. I'm sure that I would use pint jars for pickles.
