It looks like this could possibly be done. Technically speaking, each profile must correspond to a user account. But conceivably, you could build a piece of functionality that allows one user to edit another user’s profile. The key function is bp_is_my_profile(), which is checked when the profile edit screen is brought up. By default, bp_is_my_profile() only returns true if the profile belongs to the logged in account. But the output of the function is filtered. So you could do the following two things to work around the default limitation: (1) Create some sort of interface that allows other individual accounts to “own” (or be “authorized editors of”) other accounts’ profiles, probably storing that information in a piece of user metadata; (2) Filter the output of bp_is_my_profile to check against that user metadata and return true if the logged_user is an authorized editor of the displayed_user.
