Ranged Touch into Touch

[Deox]

As the title says, I'm looking for a ways to turn a ranged touch spell into a regular touch spell.

For reference, I'm trying to turn an Orb of Force into an eligible spell for the Duskblade's Arcane Channeling.

The only thing I can think of, off the top of my head, is the enlightened fist's 7th level class feature; hold ray. Unfortunately, I think that may not work for the orb spells as it pretty distinctly says ray throughout its description.

I instantly thought of Enlightened Fist, but yeah, it only applies to rays.
