I did somethin about that a very long time ago, when I only the PHB domains.
I considered the idea of having much less spells on the cleric list (about half the normal), mostly spells which dealt with protections, healing, buffing and certain divinations. Instead, I thought it would have been nice to move all the other, less "clerical" spells into domains, which at that point should have had more spells than before.
I'm afraid it won't be easy to find the notes where I've written those modified domains, but at that time I though it would have made a nice change for a setting where clerics of different deities had more different abilities.
