Considering your skill level at Oblivion, this should be no problem.
An Altmer Apprentice with magic specialization and all magic skills as Majors. The character is a member of "The Old Ones" who believe that if it isn't magic, it's crap!
Play max difficulty all the way through with no cheats.
Keep Your Character Alive (I prefer this title to Dead is Dead), i.e. no reloads if your character dies.
Last but not least, carry no possessions at all other than a set of unenchanted clothes for RP.
(Quest items that remain in your inventory are okay, just don't use them. You may make potions for sale to improve Alchemy, you just can't use them yourself. You may borrow appartus in guilds or NPC locations to make the potions, then immediately return the apparatus.)
I did an experiment with a character like this and it seems doable...if you are as good as you say. Good luck!
