no, this would not be a simple task, and we cannot offer support for it.
The way that an update page works is that the existing information is pulled from the database and displayed to the user.
when the update button is pressed, all the information is sent back to the database, including whatever changes where made.
it would take quite a bit of hand coding to determine what was really changed and what remains the same to be able to send only the changed information in an email.
