Just after I released my http://www.gamesas.com/topic/1605758-relz-skyrim-map-markers/ mod I got an idea about a similar map marker mod, but I think this is gonna be tricky perhaps impossible to do.
Anyway, this picture from the CK show you what I mean and I wonder if it's possible to create a similar map and each marker on the dragon burial mound map will show a map marker on the game map.

The player always need to have this special map in the inventory in order to show all map markers (only the dragon burial mound) on the game map, otherwise only visited map marker on the game map will be shown on the game map.
What do you think, is it possible?
