A235 No, Enlightened Fist is the only way to turn a Ray Spell (Requiring a Ranged Touch Attack Roll) into a Touch Spell (Requiring a Melee Touch Attack Roll).
It may however become possible in the future to change Ranged Touch Spells (which require a Ranged Touch Attack) into Touch Spells (which require a Melee Touch attack). Also, Enlightened Fist's ability is only applied to Ray Spells.
