Short answer: no. Inkscape is bound by what SVG specifies, and we 
currently follow the specification, so changing our blur significantly 
would be a regression. I'm not entirely sure what synfig does (I've had 
a look at the code and I'm not entirely sure why it's so visibly 
different), but I'm afraid that we cannot adopt it (entirely), even if 
we would agree that it's better in a subjective sense.

One of the differences might be the color space used for the filter (and 
blending), and this you can change in SVG using the color-interpolation 
attributes. These are unfortunately not supported in Inkscape, but I 
think most browsers do support it (not 100% sure).
