I think my first choice would be The Cosmopolite. Probably one of the best thought, demented scientists out there, with that transhuman bent and crazed background that'd make something new and fresh. Of course, I'd make up dozens of random and absurd creations, throw a lavish maddened party where pilots would have to bet their lives in a maddened maze, and wardec everyone out there.
And, on a more serious side, maybe Malcolm Cross. I'd like to get inside the incoming Caldari civil war, and with some solid arguments, start wardecking any and all caldari corps, igniting the war to full strength even as the Gallente came, and finally put a gun against Heth's head. All the while, remaining cold, planning well, and with strong arguments for everything.
Finally, Istvaan would also be a choice, as I'd love to see the skeletons in the closet of the Guiding Hand. Well, that's old-Seph speaking for me. xD
