In Oriental Adventures there is the Wu Jen class, which is pretty much a cleric who gets spells like a sorceror. They are element based and the Water school is all about healing.
If you want a ready-made list of spells for a Healing school (or healing domain), check out pg.92 of OA. The Kitsu domain might be what you are looking for; using either that restricted list, or the whole "Water" category of spells to represent a healing school.

"so as an extra twist into the idea though, what if the mage had
multiclassed as a rogue and could therefore
emulate spell ability to "pretend" it was a spell on his class list
not sure where the line gets drawn between abilities crossing over
into your other classes
ie... rogues can use a scroll providing they have ranks in use
device (or whatever its called) and roll a high enough DC to emulate
the ability. so a rogue that has succeeded in "emulating the
ability", if he is also a mage, should be able to scribe the scroll
should he not? therefore, with successful checks as a rogue in the
future, could he not then also prepare the spells and use them
later, just as if they were on his class list? and if not that, then
should at least be able to emulate it to brew healing potions or re-
scribe the scrolls"

My new question is this...
What if in addition to all of that above rouge stuff, lets say a cleric helped out with the spell "Imbue with spell ability"? The mage would then have what ever spell(s) on his spell list. Though it would be temporary, if done carefully could a mage gain permanent (written into a spell book) access to certain misc. Clerical spells?
Keeping away from the argument(s) "no cleric would do that.", and/or "no god would allow it."
Would it work?
