PowerSchool access during registration

In past years, we have blocked all access to Powerschool from outside the campus network during registration (for about five days) via a simple redirect on our PIX to a static page that says "Sorry, come back later." The problem is that teachers want to access PowerSchool from home. We are only trying to prevent sneaky students from changing their parents' contact information.
My idea is to set up the PIX block only during the hours that registration is actually happening. That prevents a student from grabbing their folder, running home, and changing their parents' phone number to their own, thus preventing parents from getting notified of their mischief. During the off-hours, or on other days when registration is not happening, we can just modify the custom parent/student login page, omitting the actual login window. Actually, we would create a copy of the custom page and just rename them when we need to change the settings.

So, when registration begins, we implement the PIX redirect. When it ends for that day, we turn off the PIX redirect and rename the custom registration login page in the custom web root folder to home.html. When registration opens again, we remove the PIX redirect, and change home.html to the "Sorry!" page. When it opens again, reinstate the PIX redirect and change home.html to the custom login page. When it's all done, remove the PIX redirect and restore the default login page.
