I've tried a similar build before and here are a few problems I encountered:
1. Sustain. WW with wastes survive because of the attack speed increase from BK swords/Istvan's Swords plus Blood Funnel rune for LoH. You will find that you will easily die even in T10 because you do not have any means of recovering life. You can add some Life on Hit stats to survive T10, and its a fun build when you can survive, but this will be the primary issue once you go even 1 torment higher.
2. Attack speed. You'll have less attack speed compared to Wastes set because you cannot use the set swords which increase your attack speed by 30%.
3. Damage. I thought that 1300% damage increase from LoN would make the lightning damage from Odyn's son/Fulminator/Sky Splitter/Thunderfury/Schafer's Hammer significant, but I learned it the hard way. The base damage increase from the set is simply not enough.
If you can get it to work, a fun build, non-the-less.
