Okay, take a look at this. I'm new to helping with builds, so cut me some slack.
Skyrim Perk Calculator - Plan the perks for your Skyrim character before spending them!
This would make you a SpellSword. Focus would be on Conjuration, 1h, and Heavy Armor. I wasn't sure what you would want to do within the Conjuration tree, so I perked it based on how I like to play.
I will usually use a Dagger or Sword in my right hand, then in my left I will conjure an Atronach followed by a Bound Sword.
Next would be Archery (range, since you are tired of Destruction) and Restoration (Resto perks will help you restore stamina and heal more quickly).
Side skills would be Smithing, Enchanting and Illusion. I wasn't sure what your lesser focuses would be, so I took a shot in the dark. I put 2 perks in Illusion mainly so you can cast spells like Muffle.
Edit: I didn't put more than 1 perk into the side skills (Enchanting, Smithing) so that you could decide if those were side-skills that you wanted. When I play, I go up the middle tree in Enchanting and I usually choose the Arcane Blacksmith perk.
Edit 2: So far my favorite race for Conjuration builds are Bretons, since they get a boost to Conjuration. However an Imperial could also be a good choice, since they have boosts to Heavy Armor, One Handed, Resto and Enchanting.
