I agree with neferhet on the obliterators. If you aren't using the Heavy Support slots, put them in 3 squads of 1. Gives a little more flexibility on weapon choices.
Veterans of the Long War can be dropped, unless you plan on playing a lot of your loyalist brethren, but it might come in handy.
I don't like all the unwieldy weapons on the Lord and Champions. You have to challenge and accept them, and you're relying on your durability to last so you can swing back. Again, this depends on what you plan to play against, but I think power swords or lightning claws would be better most of the time.
