It is possible, but I'm personally avoiding that right now. Some days ago I saw the cloud server slowing down a lot, and my internet was good; it pretty much felt like they were doing things about save files, and I'm not sure if I want to take any further risks. So far no ban is still reported to have been issued only due to save file editing, or if it is it's rare cases, and they could be people that simply didn't bypass EAC correctly (I actually haven't seen any ban report anyways since that lag I experienced). I'm also wondering if it was only me to actually have it.
