The current President of Finland? Unlikely to resign for this, though... not to mention being proposed. There would be Vaira Vīķe-Freiberga from Latvia, too, but I am ambivalent about her, and Buzek's post as President of the EP seems to exclude another new member in a top post anyway.

Of the four other names mentioned most often (Balkenende, Juncker, Verhofstadt, Lipponen), I'd like Juncker best -- not because I'd agree with him on the economy, but because he is seasoned in talks and a committed federalist, and more or less scandal-free.
