Well, I think that to keep the greencard you don't have to do all the above. Probably coming back every now and then to the US would be enough. You will have to get reentry permits to make sure they let you in if you have been out for a long time, more than a year I think it is. You can only get reentry permits from the US but they are relatively easy to get.
Keeping bank accounts and owning real state is more the stuff that's needed to keep the 'continous residence' requirement used in naturalization. When you go away like you are thinking of doing, you will lose whatever time you have accumulated of 'continous residence', if you ever came back and had kept your greencard the clock would be reset to one year plus one day. You could become a citizen 3 years and 9 months after coming back.
I maybe following your own steps soon too, and it would be nice to have the options to come back to the US if we wanted to.
