Jean-Marc,

if you don't know the structure, you will have to perform some indexing in 
order to get a unit cell. If the result is not too ambiguous, the simplest way 
would be to forget about the business to create peak shapes and use a 
single crystal approach which allows for hkl superposition or, alternatively, 
ignore positions with ambiguous index and correct the remainder for the 
multiplicity which is an easy function of hkl. SHELX may be useful, it works 
with I not F.
