My advice would be to put Mercury at perihelion, and set up your
point of view somewhere along the morning terminator. From the Sun's
point of view, Mercury will then be rotating "backwards" (i.e., the
Sun will set back down in the east). Then set the date back a couple
of Earth weeks (to before the first sunrise) and watch the show.
