This is exactly how European companies do when they acquire American ones, especially "Tech" companies that have well-paid technical staff. You can hire in Eastern Europe for far less, and can hire in Western Europe for still a significant bargain compared to what engineers and associated people make in California - plus, dealing with an 8+ hour time difference is brutal compared to keeping it all in Europe.

A friend I know is going through such an acquisition, funny thing is it's a European company acquiring his, but owned by an American PE firm. The American PE firm knows that cutting-edge tech is developed by expensive engineers on the West Coast, but when it's time to milk a more mature company for cash flow, you want cheaper European staff.
