I don't think this will affect the GOP choice for VP. Hillary is a very polarizing figure. Obama lacks substance. This ticket can capture the northeast, parts of the left coast, and the very corrupt Illinois, but not much more. They can kiss the south and its 110 electoral votes goodbye. I doubt they can capture the plains and the midwest. In the end, they might get around 200 electoral votes.
Of course these are strictly my speculations. I have no sources, references, or links.
