I had the same idea in fact, but I realized that my graphics skills are
not sufficient to produce an acceptable result. ;) I had the following
idea: Why not organize a public submission period and then hold a public
poll to find a canonical logo? I imagine it like this:

 1. Provide a trusted public submission portal (e.g. “mail your
    submission to logos at”).
 2. Announce submission deadline on all public CL forums (mailing lists,
    nntp, reddit, planet lisp, ...)
 3. Hold a public poll on the submitted logos (again announce on all
 4. Declare the most popular the new community logo

I would volunteer to organize the process, and I think is in a
position to provide the necesary “neutral ground”. I think there are some
benefits to this approach as we can outsource the graphical talent and
get a result that the community decided on. :)
