You're a patch late for a magicka tanks. I suppose they're still possible, but their heyday is past.
Tanky DPS is still possible. Imperial is not the best choice for a magicka character. Altmer, Breton or Dunmer are, as they're the races with bonuses to max magicka. Still, Imperial's bonuses to health and stamina will definitely help. If you're set on Imperial, you can do well with one.
Magicka casters generally wear 5 pieces of light armor, due to the passives. The other two can be more light, or any mix of heavy and medium. Personally, I wear 5L/ 1H/ 1M. All light is too flimsy, and there are some nice passives in the Undaunted line that benefit someone wearing a mix. In some cases (PvP), a heavy-armor sorc who uses drink instead of food can also be viable. I had one of these tear me up good the other day
If you want to do a true tank, you'll need to be stamina-based. You will still use magicka for a few key buffs (Lightning Form, Critical Surge). But your key resource pool absolutely should be stamina. Note, if you do this, then Imperial is definitely the best race. Stamina builds are really good now, so this is a great time to start one
