The shadows beneath units , possible to alter shadows bigger/smaller or turn them off clientside ?

The shadows beneath units , Is it possible to alter shadows bigger/smaller or turn them off clientside ?
Or are they a part of each sprite ?

To add more blur to them and make them bigger/thicker so that they get more a feel of a bulk and a
united shadow of the whole unit instead of small very (non realistic look, personal opinion ) sharp shadows that are
on  the cavalry and infantry like in the picture below ?


More to get the look like this:


As they look now it doesnt give a united feel for the unit, and I think this would
improve to  immersion in the game and the overall feel of it.


Even the old Imperial glory had a more blurred and bigger shadow beneath the unit which also
made it look quite neat, mostly on the cav, even though the game wasnt perhaps that great.



Any comments on this subject from readers of the post would be nice

They are part of the sprite and cannot be altered or turned off unless you edit the sprite itself.
