Cleric Domain Spells for Summoners

[Frank]

There are two cleric domains which seem geared towards summoning- Portal and Animal. Neither of them are able to get a summon that lasts 24 hours as a bonus, even with SF and GSF Conjuration. It'd be nice to be able to have a summoned 'companion' the way wizards, sorcerers and druids do.

My suggestion would be to give the Animal domain the ability to cast summon swarm as a 3rd level spell and for the Portal domain to get Lesser Planar Binding as a 4th level spell. A cleric focused on animals should be able to thematically have little scurrying friends with them, and I like the idea of a Portal summoner who can bring in a single Summon Creature 3 to hang around. In my experience as a Portal cleric, the Summon Creature 3 creatures don't tend to be strong enough or have enough survivability to be unbalancing as a  24 hour spell. As a fifth level spell, I don't really think any cleric - even a summoner focus- would take it normally.
