Permissions Plugins!

Hey Guys! I have an idea for a plugin that would be pretty cool. Here we go(This plugin isn't for me, just a cool idea). A plugin that is compatible with bpermissions, zpermissions, permissionsex, groupmanager, etc. that allows you to make a custom command such as "/staffmode" and "/playermode". You can have the custom permissions groups in permissionsex for example and when you do /staffmode you will gain the permissions in your group(moderator for example) such as /ban, /kick, etc. And when you do /playermode you will lose all those commands and ONLY have the permissions from default group. So basically this plugin allows you to have your staff be able to play the game without being too OP because of their permissions that they can't change. If you have any questions, just ask, please!!!! Thanks Guys!
