I think I found a semi solution because I think although UNA only allows one admin profile you can give another profile all the same permissions including switch to another profile. Login under admin and go to permissions app and upgrade your profile to moderator  using the admin profile and give the moderator permission to  "Switch to any profile". This would give a moderator the ability to become the admin profile. Also Admins can create another profile that has same Admin powers in the same menu I showed you "Create New Profile".
