Instead of Reach Spell, if you have a few turn attempts have a look at Divine Ward (PH2). You 'ward' one ally (and additional ones at the cost of a turn attempt) and then, by spending a turn attempt, can cast a 'touch' spell on a warded ally as a Range: Close spell. So slightly more limited application as you can only do one or two warded creatures, but 1) no bump to the level of the spell, 2) no need to hit with a ray and 3) no need to prepare in advance, or spend a full round action metamagicing a converted cure spell.
Of course if you can use Divine Metamagic and/or Divine Spellpower, take those. Anything banned in Living Greyhawk is on the overpowered side of things! (I don't agree that DSP is that overpowered, but it has the advantage of getting through SR more easily. DMM can be very very powerful. Even one free quicken of your highest level spell a day can make an enormous difference, and it's a cheap way of getting it compared with Sudden Quicken.
