The problem you are going to run into with wands is there are no crafting recipes to "Boost" them. Not that staff has a lot of boost recipes either, but at least there are 1-2.
That being said, I think Staff of Magus needs to adjusted to have the same range as any "Spell" you cast and to have a 0 turn cool down. That way you are trading off the "utility" of having 2 damage types with a dual wand setup for the "utility" of having more range. IE. the "Staff" should be the "Sniper Rifle" of the magic world, and the wand the "Pistol". Wands need to have their range nerfed a little as well.
Maybe someone will do a re-balance mod once the new mod tools come out.
