I knew a captain who would go back and forth to Spain. He would bid his schedule to work the last half of the month, then swap to the first half the next month, and so on. So would have 4 weeks on, then 4 weeks off.

The wife wants to live in Europe before retirement so I would attempt to commute but cant see any way a weekly commute would work without being fatigued. Once or maybe twice a month maybe.
