And before anyone says she did, I mean officially, not morganatically. Lets say Elizabeth meets the future Peter III and finds him wanting as an heir, or decides it would be better to put him on the Swedish throne (which would be VERY interesting indeed). Either way Elizabeth decides she must marry and produce an heir. So who does she pick? A Russian nobleman? A German Prince? Or perhaps an Italian or even British or Spanish? Who are the most likely candidates for the Empress's hand? Also, what would her consort's title be? Grand Duke? Prince Consort? Or even Emperor?
