If servers accepted a hash of a password instead of the actual password then the hash becomes the password. Ie, possession of the hash is equivalent to possession of the password since it can be used to authenticate.

Therefore, this is no different than storing them in plaintext. Furthermore, it would mean that if the hashes got stolen because a server was compromised those could be used as passwords and that would make it pointless to hash them in the first place.

In other words, no, that wouldn't work.
