Given the current uncertainty over whether Viktor Y. won the Ukrainian presidential election or whether Viktor Y. won it, wouldn't it be an easier option just to split The Ukraine down the middle as Viktor Y. got most of his votes in the West and Viktor Y. got most of his in the East. One half (those who voted for Viktor Y.) get the East (to be re-named Novo-Rossiya) and the other half (those who voted for Viktor Y.) get the western half (to be re-named Wielka-Polska)
That way everyone is happy and everyone is a Viktor.
