It will be difficult, but no impossible. You'll have to get current again - in other words, pay for some SIM time. Personally, I wouldn't do it unless I had an offer of employment.
With that in mind, ANA is hiring 767 F/O's and Captains. Also, Korean Air is hiring for the 777. To get hired you need a 777 rating, or a 757/767 rating, then you will have to pay for your 777 rating after they've offered you a position.
Otherwise, check with the various agencies - Parc, Rishworth, Direct Personell, etc. Their websites usually have info for fellows with your circumstances.
Cheers, and good luck.
