(Almost) everything is possible in matter of software development, but IMHO 
the above would be a horrible hack in the code, whereas you can simply edit a 
text file to indicate your will.

Furthermore " ogr2ogr -dialect sqlite dst.shp src.vrt -sql "someSQL" " is 
something valid currently and it means to run someSQL with the sqlite dialect 
on top of src.vrt would naturally return (the fact that src.vrt can run some 
SQL internally is something that ogr2ogr doesn't know).
