What if you combined the Wizard and Mage?

[Zuranthium]

To be honest, if we're talking about combining the classes without any other game changes, you could give Wizards all of the non-pet Mage spells and the class wouldn't be overpowered at all.

...and then give Druids all of the classic-era Mage pets (starting at Level 9, with the Level 4 pets)...and that class would still be relatively weak at the higher levels.
