I think security questions are primarily a bad idea.
As I understand it, hilariousandco is able to unlock these (though don't take my word for it) - so that should be dealt with quite quickly for legitimate cases as he's very efficient normally (for anyone wanting an account unlocked, signing a staked address will probably be enough proof to have your account back in your posession).
I know they will but have you considered the amount of time a member will need to wait to get their account back? It's ridiculously lengthy (from the experience of seeing others case around) As I understand it, hilariousandco is able to unlock these (though don't take my word for it) - so that should be dealt with quite quickly for legitimate cases as he's very efficient normally (for anyone wanting an account unlocked, signing a staked address will probably be enough proof to have your account back in your posession).
I have only seen cases of people needing theymos/Cyrus' help to recover their account. NOT hilariousandco and he seems to go quite quickly as he doesn't have as much of a backlog as theymos does for unlocking accounts.
Update: Just took the risk and it did work!!! 
I feel good now. Thanks @SFR10
That's helpful. So all it took was deleting those two fields (did you get a notification as to the change)? I feel good now. Thanks @SFR10
