the first thing that comes to mind with a post like yours is: you need to make up your mind
either commit to showing your face and accepting the possibility that someone you know might see you, or commit to a different way of approaching the problem
there are only 2 straightforward solutions:
1. have someone else be the "face of the channel", while you write the script and deal with all the other channel-related stuff. (could be a friend doing it, finding someone here on yttalk, reddit, doing a collab or hiring someone through fiverr, etc.)
2. trying to make it work while not showing your face (provided youre comfortable with doing voiceovers instead) - you cant know unless you try, right?
logically, because you prefer to remain anonymous, i guess the best course of action would be to do the 2 option first, see what happens, and if you find little success, try the 1 option
just my 2 cents
