No. The only ones with WE are admins and above (+me&naith). Even with heavily restricted access to WE we've had serveral fuckups in the past.
Furtermore, in theory, adding this would grant all moderators WE permissions as they can add and remove themselves from WGs as they wish.

As I'm not part of the MC staff anymore I will not reject this idea straight away, although naith and stoux will probably have similair thoughts on this.
