I don't think most people have " got" what it is your saying/ asking. As some have suggested you could observe the memorial in the privacy of your own home, put that doesn't solve the issue of what to do at the memorial.
If you feel it is a rejection/ insult to Christ to pass the bread and wine over, then do partake. As a JW in good standing they will most definitely "count" you as believing you are one of The anointed. Just let them believe what they wish.
What you must NOT do if you don't want to be DF is say you DO NOT believe you are anointed but that Jesus IS your mediator. You will be seen as rejecting WTBTS doctrine.
