An Urget Needed module or tool

Drupal is a very powerful CMS but it misses one big feature. Many modules are not working more. So i thought a lot about updating modules. I read documentation about upgrading modules but they are not useful for most users who are not programmers. So i think it will be excellent if you write a plugin or tool for upgrading modules from Drupal 5 & 6 to 7 automatically. It only needs that you write a program that converts updated functions and replace them. Whats your idea about it?
