Making the cleric a limited-list caster brings them too close to the favored soul and sorcerer, I think.
While I'd definately think about a spheres system and if some worked on out for me I might use it, I don't think that it worked that well in 2e and it would be a lot of work to successfully create one for 3e. It would probably vastly increase the number of spells that you'd need in your 'core'.
Moreover, as I stated in my first post, I'm only concerned with a very limited set of classes. So if I step on the toes of the 'favored soul' class - a class I honestly wasn't aware of before today - it doesn't bother me at all. I don't plan on using them. Looking at the class its exactly the sort of class I don't want to create. "You become an angel" is far too narrow of a concept for a class. It's a subclass of a subclass, and I already have ways to get there with existing rules and could create more on whim if a player had that as a concept.
The really interesting question is, "Does the cleric get out of tier 1 if I go this route?"
