I have a few ideas, but they're not all AD champs building AP and vice versa.

1.) Hitter Diana. Not exactly something new, but it works. This takes advantage of Diana's passive, and the fact that she generally finds ways to end up right next to you. Works if the team already has an APC, or just needs someone to split-push (Moonsilver Blade works on towers)  Build is Berserker's Greaves + Nashor's Tooth + Guinsoo's Rageblade + Malady + Hextech Gunblade + Rabaddon's Deathcap/ Lich Bane

2.) Lifesteal Irelia. My general build for Irelia. Nobady complains, since it works so damn well. Gives Irelia massive sustain (82% lifesteal) and AOE presence, pushing power, and incredible chasing ability, since Bladesurge will instagib ranged minions at full HP allowing you to Bladesurge repeatedly. However, build lacks non lifesteal survivability, so if you get blinded, or CC'ed by 5 champs, it's probably over for you. Build is: Mercury's Treads/Any boots + 4x  The Bloodthrister + Ravenous Hydra

3.) Tanky Anivia. I got the idea from a friend. Build gives decent AP, Armor, Magic Resist, HP and two more ways to cheat death. Three actually. But the third stops at level 18. Build is: Boots of your choice + Zhonya's Hourglass + Rylai's Crystal Scepter + Rod of Ages + Guardian Angel + Rabaddon's Deathcap/ Warmog's Armor

4.) DPS Darius/ Jarvan IV/ Shyvana. My general build for these three. Not really new, per se, but not really oftenly used either. Gives these champions DPS to keep up with the opposition, even if the opposition is the same champion, only better farmed, since they build tankiness immediately. It does, however, make you a prime target in the mid game. Build is: Berserker's Greaves (preferably with Furor, to help with chasing) + 2x The Bloodthrister + Infinity Edge + Warmog's Armor + Randuin's Omen

5.) I don't give a damn about how much armor you have build. Credit goes to Vapora_Dark. Generally built on Riven and Talon, but I also use this on Vi, Varus and other champs who are countered with armor. Gives 50% armor penetration, 250 HP, a little attack speed and the ability to reduce armor by 5% everytime you deal physical damage. Build is: The Black Cleaver + Last Whisper + whatever you build on Physical damage dealers.
