I second these suggestions.  In fact you might want to simply start the
shell with a certain environment variable set which will trigger the

  screen -t mytitle env PRINT_BANNER=1 bash

In .bashrc:

  if [ -n "$PRINT_BANNER" ]; then
    banner ...
    unset PRINT_BANNER

You could even use the existing $STY and $WINDOW variables that screen
itself sets (though subshells would print the banner too).
