Loris,
Instead of using lith film, you may want to consider using TechPan 
sheets with D19 + K Thiocyanate (or added NaS) as the first developer, 
and D19 without K Thiocyanate (or NaS)  as the second developer.  That 
combination gives a very lith-like final reversal image, BUT avoids the 
grain clumping you are seeing.  Part of that is simply an outgrowth of 
greater consistency of distribution of the silver through the TechPan 
emulsion (better quality control).
In any case, placing a black sheet beneath the negative would help 
decrease both base fog and halation effects in the enlarged sheet.
