I understand everyone would prefer your solution and it might just work (at least for a while) but a lot of people seem to lose one of their farms sooner or later. Whether it's something they do or a next update of the iOS or the game but a lot of people lose their farms and not all the time will they be able to get it back. A factory restore and new GC ID is the way to go.
Also keep the farms seperated at all times and don't switch them around. It's 1 farm per device / GC ID.
