A pro to teaching what you are claiming as "poetry" from it would be to help kids understand how to read works like Chauser and Shakespeare ( if you used KJV). The con would be with science. Kids would grow up thinking nonsense like "rabbits chew the cud" (Leviticus). Ultimately, there is no real "pro" to teaching it. Experts in the fields you talk about generally agree on the bigger issue. Biblical scholars can't even agree on the most trivial things, which doesn't help the credibility of biblical "science."
