I'd like individual divine spellcasters have a list of no more than 12 spells per level (preferably 8, actually). Probably something handled via a spheres or domain setup. With a handful of spells (say 4-5 per spell level) being "generic" spells available to all casters (say, all cure/inflict spells). If you want to add in a spell from another book, the caster needs to swap out a spell from the "core" list.
The only issue becomes players not only having to search through the spell list, but also seeing if that spell is in their domain. It puts more emphasis on having "the right domains", and therefore choosing (or making) a god who gives you the right domains for the spell list you want to be able to use. 2E had this issue, and I remember as a DM that some of the domains my made-up gods ended with gave them some horrible spell lists for players.
