I am thinking of using robes, hood, two handed sword and magic (defensive and offensive both).
Alteration provide armor spells but downside is have to always cast it during combat, and to cast it is to unsheathe weapon, if combat is lengthy one it could be a problem. But nice having passive magic resistance (if the character is a Breton it will be nicer) and the best way in combat is not to get hit at all, wearing robes move faster.
Alteration also provide Telekinesis but little use of it in game. (Funnily detect things and Telekinesis fall into Alteration but some are Jedi powers)
Restoration give healing, armor rating and magic resistance. But downside is we must cast it to get the effect, meaning unsheathing our weapon. Since two handed weapon using both hand, no animation for holding it one hand and cast spell in the other hand. That could be a problem in lengthy combat
Illusion give some sort of Jedi power such as mind controlling, stealth and such things.
Destruction give some sort of Sith power, lightning spells especially, and if dual cast will be like the emperor Palpatine
Conjuration magic, summoning familiars and Soul Trap (but i am not fancy Conjuration school)
Speech provide another Jedi/Sith trait that is being diplomatic and manipulative
Smith is not so important, just to upgrade weapons, masks, bracers and boots
Enchantment is vital because of no armor, relying on weapon power and other enchantments
Unfortunately there is no Acrobatic in Skyrim, not like in Oblivion, so there is no fancy jumping like Jedi/Sith do.
Shouts like Fus Roh Dah do look like overpowered Force Push, all other Shouts are useful and some do like Jedi powers. Downside is it have long cooldown
I am thinking on Mage Sign for bonus 20% experience in magic, because will be relying on spells and must have higher level of defensive or offensive spells, combat will level eventually and what important is Two Handed,Block up to bash perks and Smith to upgrade weapon, masks, bracers and boots.
Advantage
- fast movement
- carrying capacity
- can use magic and melee respectively
- high armor rating due spells
- high magicka regeneration from robes
- high magic resistance passively and/or due spells
- can apply poison on weapon
- look cool in robe and hood (and masks but there is a bug with masks)
Disadvantage
- must casting spells for armor rating
- casting spells unsheathe two handed weapon
- spells effect is temporarily, must cast again when duration is over
- need high level defensive spells quickly
- no passive armor bonus due armor wearing
- busy self with opening the menus or favorite button in combat
- perk spread is complicated, if messed up then it will mess up
