== Lost Tradition ==
Probably the simplest solution is a 3rd party feat from Bastards and Bloodlines:

      '''''Lost Tradition'''''
      You are descended from a group of spellcasters who had very different ways of mastering magic, and you follow in their tradition.
      
      '''Prerequisite:''' Must be taken at 1st-level
      '''Benefits:''' Choose one spellcasting class. You may change which ability score governs spellcasting with that class. That ability cannot be changed again.
      For example, Elric is a Talrik cleric. He takes the Lost Tradition feat and chooses to base his clerical spellcasting on Charisma instead of Wisdom. He now uses
      his Charisma score to determine his bonus spells, spell save DCs, maximum spell level he may cast, and any other calculation regarding his cleric spells.
      '''Special:''' You can take this feat only at 1st level.

Take a level 1 wizard. Take Lost Tradition. Pick Strength as your casting Ability.

You are now Muscle Wizard.
