Hello Ronald,

The maximum width (east-west) of the Grand Gallery is circa. 4 royal cubits/6.9 feet.
Because the Pyramid's builders were able to span the width of the King's Chamber (circa. 10 royal cubits/17.2 feet) with a single block, I would suggest that your explanation is most unlikely.

Regards,
