Ive done it numerous times with 2 skoria, 5 twice born star, 3 willpower jewelry, 2 torug swords and 1 torug resto staff (for extra magicka regen and emergy shielding, you can use harness magicka now instead). Biggest problem for mag templar is magicka regen, if you run out of juice you can't jab and then you die, so depending on your CP you may want some magicka regen on your enchants.
Now i do it with my usual pve gear, 5 moondancer, 5 twice born, 2 skoria, dual swords and inferno staff backbar. Use jabs for healing and harness magicka for emergencies. The new purple food from the festival is really good, gives you some hp, magicka and a lot of magicka regen, but you are low on health, there is where tbs and skoria come very handy with the hp bonuses.
