This thread is bound to fail for exactly the same reason noone has picked up on the four year old RFC 343: it's expressing the wish for change, but leaving everything to others.
Come on, if you want a change, come with a proposal better than "let's do something". Pick a symbol. Make some sketches. Write a paragraph or two why it's a good symbol. People might not like it, and come up with other proposals. But get the ball rolling. Don't ask others to kick the ball first.
(How about a tarpit? It looks disgusting from the outside, but once you dive in, it really gets stuck to you, and you'll never leave...)
