Let's inject some reality in this thread.
They won't go to Europe. The cars are in Asia and are staying there until they are scheduled to leave. But even if they could go to Europe, there isn't any options outside 1 or 2 venues.
Estoril, Zolder, Zandvoort, Jerez, Valencia, Algarve, Mugello and Imola (one nobody has mentioned yet, oddly) do not hold the required licenses to host an F1 race. Some hold licenses which allow tests (Grade 1A i think they are referred to), but they don't hold Grade 1s. Paul Ricard may hold a Grade 1, but it doesn't have facilities for a race.
The only option they could possibly look at is Fuji, but even then the logistics of it are now an impossibility. They'd have 1 and a half weeks to setup *everything*. Not happening.
