Do you think there is a chance SHA-2 could have an NSA backdoor like SHA-1 and if it did would that pose a threat to the chain or would there just be a consensus to upgrade?

SHA-1 doesn't have an NSA backdoor. It's just insecure.
There's a good chance SHA-256 remains secure for the rest of our lives. We have gotten better at cryptography, and SHA-256 has lasted much longer than SHA-1 did.
