The best way to undo some of the damage done by the Watchtower is to be there for those who are on their way out or newly out. I have been in contact with many of them, some on the verge of suicide. Thankfully, they've all made it through, and they're all reaching out to others.
By screwing up the memorial, you'll be showing disrespect to Jesus in the minds of jws and not to the Watchtower, where the disrespect rightly belongs.
