Its possible - but will be very rough. When you start you'll be reserve so you will need to commute in just to sit and wait for a possible call. Also if you only have 2 days off commuting home may possibly mean 5 or 6 hours at home before commuting back. That being said I know of a flight attendant at my airline that commutes from singapore and at my last airline there was a puerto rico commuter and an England commuter.

Once you hold a line you should be able to trade/swap trips to get 2 or 3 weeks of flying followed by 1 or 2 weeks off. (Save for the rest between trips in a crashpad).

Also I think you have to pay the international taxes if your jump-seating out of the country, but I don't know for sure.

Difficult yes, but not impossible.

Hope this helps.
