Lets look at magic for the olympians, shall we?
You are using the death rune for war gods? Why not use the Disorder rune instead and use death only for Hades?
Here are my suggestions: (i'm just listing what I find appropriate, lets pick a number for balance reasons later)
Aphrodite
Magic
Common: Becalm, Dullblade, Glamour, Heal,
Divine: Aphrodisiac, Befuddle, Blessing, Disarm, Heal Body, Soul Sight
Apollo (apollo is also the good of medicine and healing, but also illness and disease, in the Illiad, he fires arrows with plague at the troops of Agamemnon. He is also the patron of oracles, he should probably have the truth rune).
Magic
Common: Cauterise, Fate, Firearrow, Ignite, Light, Lucky MultiMissile,
Divine: Cure Disease, Eclipse, Sunspear, Sureshot.
Ares
Magic
Common: Bladesharp, Demoralise, Fanaticism, Pierce, Strength,
Divine: Berserk, Blessing, DIsmiss magic, Fear, Madness, True (spear or sword)
Artemis (artemis also has a lot to do with the moon, she should perhaps have that rune, although I'm not sure which of the others to remove)
Magic
Common: Beast call, Bestial Enhancement, Boon of lasting night, Clear path, Multimissile.
Divine: Beast form (bears and deers are most appropriate), Eclipse, Heal wound, Sureshot
Athena
Magic
Common Magic: Abacus, Armoursmiths boon, Coordination, Endurance, Parry, Protection.

Demeter (also controls the cycle of life/death, hence resurrect and hand of death).

), Bless Crops, Cure Poison, Illusion, Madness.

(no communication rune on the god of diplomacy?) (I know he is pretty much the god of everything, so we should perhaps settle on a few select choices?)
