Elites and above should receive a command similar to chest, but for accessing their enderchest.
Implementing it:
The command for it is "/enderchest", it is a command brought from Essentials, which Meepcraft already has.
PEX Perm: essentials.enderchest
This PEX Permission will allow players to open their own enderchests, but will not allow them to see or modify enderchests of other players.
With adding this permission, mods may want to be able to check their enderchests as well. I believe they are already able to do so, but if not:
essentials.enderchest.others ...Allows you to see the contents of another players enderchest.
essentials.enderchest.modify ...Allows you to modify the contents of another players enderchest.
Thanks for Considering
