Ok, I know it sounds crazy. But what if they put a correctly sized explosive(s) deep enough below and along the spine to blow and then fill the area with water, reducing the rheological load? We're talking about 100 feet underneath the canal bed, and do it with a shaped charge that'll be more optimal for the task. Just thinking about fast <1 week methods.
I was wondering if it is sand, can it be liquefied using vibration around the hull to help loosen it? Something like what they use to vibrate concrete while pouring it. https://www.youtube.com/watch?v=tV4sTbpa7Hc
So... you want to be the one responsible if it doesn't go as planned? Further blocking the canal, let alone damages to the ship and cargo on board.
Theres a reason wacky, dangerous ideas happen in the movies and not real life. The consequences of trying to look clever and failing are pretty severe.
