I have the 21 ASPH which has the same mount and hood, and I have no problem 
mounting the hood over any of my E55 filters (HOYA SMC's) and in fact a Leica 
UVa filter lives permanently on the lens (except when I use another filter of 
course).  The few B+W filters I have seem to have rather thick mounts, so 
perhaps that's the problem.  As to vignetting, I also use the Leica Universal 
Polarizer on my 21 ASPH (it has it's own hood).  It does not physically 
vignette but you do get an uneven effect on a blue sky due to the lens' 
coverage (I only use the pola to reduce reflections).
You might try using a filter with a thinner mount (I think even B+W make them 
specially for ultrawide lenses).
