Interesting stuff there, does the macro lenses effect distant focus at all? or does this just zoom in the image without effecting the focus in any way...
Diopters will make the image a little larger, but they are mainly used for changing focus distance. More useful when shooting with a camcorder with zoom. Without the diopter, most camcorders need around 36 inches to fully zoom. A +4 diopter will let the camcorder fully zoom from around 10 inches.
