You cannot prolong the keys from 512 to 2048 bits, so you will need to generate a completely new key. The idea of additionally signing the new key with the old one is perfectly valid in theory. On the other hand: If you have to update the key of your CA because the old one is too short (= not secure any more), then the trust by such a signature is limited. And: You might run into troubles with some other clients than IE or Outlook. The handling of cross certificates is pretty poor in many applications.
