In sum, I think it's feasible but the criteria is that one must get to landside asap to print the boarding pass before 60 minutes cut-off. The most time-consuming part is the deplaning and immigration, afterwards it's a simple process and it's relatively easy to get back to airside by 60 minutes before departure (but then no lounge or relax time). You can sort of jump the queue on immigration and security if you beg and show them the boarding pass if you're seriously late.
Thanks for sharing. Never done this, but just wondering if I could suggest, if getting a pass T-60 is the biggest hurdle, perhaps paying for a small amount of internet on the plane to check in and print the pass or having a friend/family member check in for you would be an option?
The kiosks seem to print tickets up to departure as long as you're checked in, but I've only done that domestically.
