What I would suggest (being a project leader) is put a comment on the profile about your interested in cleaning it up. The project leaders will see that and can give you guidance if they have concerns, or let you have at it if they are comfortable. I would suggest doing edits in small chunks and save. Partly for ease of seeing changes made in groups, and partly so you don't lose much if there is a glitch (I've learned from lots of experience editing our 5 star and PPP profiles). I try to group my edits by type, such as reordered in chrono order, made inline refs, made a children list, removed duplicate sources, made named sources, or even a broad type such as source cleanup. Be sure to enter the changes in the explain your changes box so if someone (a project leader or manager) can easily follow what you are doing.
