Well like I mentioned, it would essentially be a ranger as far as armor and weapon selection, and it would essentially fill the same role. Paladins are plate wearing tanks that heal. Shadow Knights are plate wearing tanks that un-heal. Rangers are chain wearing dps that have naturey spells, so the Battle Mage would be chain wearing dps that have arcane spells.

I would imagine it would have a direct damage line of spells from the wizard class, just a couple few spell levels behind. It would have a fire damage shield to match the rangers thorny shield. Have the shield line of spells that an arcane caster gets to balance the skin line of spells that rangers get. Maybe instead of having the utility buffs that a ranger borrows from the druid, it could have something that is unique to wizards, like maybe self gates or something.
