We could add support for login_hint query param so you can have the username/email field on the login form pre-filled for the user, so once a user has to authenticate you redirect to login on KC and all they would have to do is enter their password.

If you bypass the login forms you'd loose SSO, multi-factor support, required actions, recover password, etc, etc, etc..

As Bill mentioned we provide very flexible login forms that can be templated using either just css or even FreeMarker templates if you need a lot of customization, so you should be able to make the login form integrate well with your website.
