Yes.  It might be done by adding an ANTLR specification that
constructors will generate code like this.

public MyParser() {
   antlrMyParser();
}
public void antlrMyParser() {
   ...
}

Then in the .g file the user could write a constructor that included a
call to the ANTLR-generated antlrMyParser().  ANTLR would then have to
recognize constructors (perhaps by an option) and suppress its
generation of them.

But overall I don't think that this complexity is justified.  I've
reorganized my code to avoid this problem.  Another solution would
have been to edit the generated code.
