Emek's flip power has a cost of Flip Emek -> therefore you can pay that cost. When resolving the effect you coplete as much as possible. Meaning if you have no cards in hand you don't discard, but your opponent does.
For Wubb's again it falls under the category of completing everything possible.
2, Destroy Wub's Cursed Hexblade -> is the cost. So you can definitely do that, any WOTF ally is targetable so you can chose them as the target.
The Destroy target ally effect will attempt to resolve and will of the forsaken will prevent it. There is not a IF you do statement in wub's so in my opinion you would be able to put an ally with the same name as that ally into your party from graveyard.
