I’ve got a theory about a possible “worldwide” mega-tsunami. Just a theory but I’m hoping somebody did some related research, once upon a time.
In H.G. Wells’ story “The Man Who Could Work Miracles” the protagonist orders the Earth to stop spinning. Big mistake. Disaster of all sorts ensues, including a worldwide mega-tsunami when the oceans leap out of their beds and roar across the continents.
Could a BIG asteroid, striking the Earth at an angle, cause a lesser version of the same disaster?
Like I said, just a theory. But most cultures have a legend about a massive flood, roughly around the same time in history.
Why are you availing yourself of a more-specified (unnecessarily complicated) scenario?
Occam's Razor!
No need to slow down the rotation of the Earth even only a smidgen! Even an only smallish asteroid - say 5 km in diameter - would create a splash (and possibly unleash earthquakes and resultant tsunamis) sufficient to explain all the phenomena you are trying to explain.

Immanuel Velikovsky got crucified by the scientific community when he wrote Worlds in Collision in 1950.
Most of it makes more sense to me than the current expalanations.
