Well, erm, how far do we want to get into fine-tuning?   
    
OK, it looks like you only want one glyph at a time.     
    
Torsten wanted several; he used markup to declare them in a group.   
And to keep a group looking cohesive he wanted more spacing on the left.   
The    interval-translate   hack killed two birds with one stone:   
- put the group closer to its note     
- effectively padded it on the left.    
    
But if you want less (or no) padding on the left, try this instead:        
    
 \override Accidental #'X-extent = #(lambda (grob)
   (let ((iv (ly:stencil-extent (ly:text-interface::print grob) X)))
     (cons (- (interval-start iv) 0.1) (- (interval-end iv) 0.7))))
    
It lets you adjust left (0.1)  and right (0.7)  separately.    
    
    
    
I don't want to get involved in more detailed fine-tuning, 
but I did try out a test case based on your gis measure:   
 juxtapose feta and HE and then get them to match (see feta_HE.png).     
That is how I arrived at the values above.     
But of course that is just for the sharp sign ...    
    
And before I could start measuring the two sets of spacing, 
I found I had to shrink the HE sharp to make it comparable!   
    
 \override Accidental #'font-size = #-1
    
    
    
Cheers, 
Robin
