wp-login.php trouble removing admin style

For security sometimes I password protect the wp-admin folder on the server. However this is causing a problem when subscribers try to log in via the wp-login.php

Line 64 and 65 or wp-login.php:

wp_admin_css( 'wp-admin', true );
wp_admin_css( 'colors-fresh', true );

I can comment out these two lines then copy the css to my template directory or even write my own styling

then re-apply it to the page with an action
add_action('login_head', 'childtheme_custom_login');
Codex Reference ‘login_head’

now wp-login.php calling the css from my template directory and does not require the wp-admin folder password because it is no longer trying to access files.

However, that’s where I am stuck. I do not want to edit core wordpress files. Even if its a simple edit.

How can I achieve the same result solely from my functions.php ?

I have tried lots of action hooks, deregistering styles, etc nothing seems to work.

the wp_admin_css calls wp_print_styles and I can’t seem to hook into that properly either. When I add an action to wp_print_styles and reload the page, it does not call the applied action.
