Long Casement Windows on First Floor

The casement windows on the facade of the house are 2.1x 900 which means there is a safety issue. I know I need restrictors for the windows but my husband says lets put a wrought iron grill over the lower portion of the opening and get the windows to open to the inside. Yeah sure!!!!!!!!!How are my flyscreen and plantation shutters supposed to open? Will the grill give me enough space to open the casements to the outside? I cannot change the style of window as it will wreck the facade of the house.
