Great idea Endo!

I have not tested it in game, but you should be able to create a god file with a name like...
BARIAN_2_A_EA_

...which can be read as "Add (A) Ulm (2) for Early Age (EA)", and would only adjust the luck scales for the given nation with the code below:
#scale_unluck 2 -3

Or you could randomize the scales a little with:

@3
#scale_chaos 2 -1
#scale_chaos 2 -2
#scale_chaos 2 -3
@3
#scale_lazy 2 -1
#scale_lazy 2 -2
#scale_lazy 2 -3

#scale_unluck 2 -3


I generated the file name and code in a few seconds with the GodEditor. Let me know if that doesn't work or if I am misunderstanding how the map code for scales work.
