Problem is that by swapping out everytime, once you buy your glyphs its unlikely that you will buy any more so it won't be cost effective.
Knowing Blizzard they will probably try for somewhere in the middle and allow us to swap out greater glyphs, but the minor and lesser glyphs will have to be replaced each time.
