In my opinion modification is not possible due to iron core transformer used for voltage conversion at 50 cycle working frequency, Whereas in modified sine wave inverter, dust core high frequency transformer is used.
But if you have some knowledge of practical Electronics there is an article by Mr Swagatam where he explore his idea for conversion
Here is the link.
