Is IFR navaid training of the type that happens overhead a site like MNG possible in it's present form in E, especially if the controller is responsible for a much larger sector, thus doesn't have the time to concentrate on positively separating multiple constantly level-changing aircraft in close proximity? The only result I can see is that access is going to be incredibly restricted, to the point that training will just move to somewhere else in G where you can actually get in and get it done when you want to get it done.
