All this would be rather inimical to any living thing, including those on
the ark, and would disrupt the layering of water necessary for
Woodemoreappe's suggestion of how aquatic animals of different salinity
tolerances could survive.
To account for the observed pattern in a shorter period of time, the
production of 14C would have to be significantly lower in the past (in
addition to the problem of no evidence for rapid change in 14C). Unless
the rate of cosmic ray input was lower (less of a problem for you than for
anyone who claims the universe is a few thousand years old), the only way
to do this would be to decrease either the supply of nitrogen (and drastic
changes in atmospheric gas concentrations would be rather harmful to most
organisms, such as plants and animals) or decrease the amount of
interaction between cosmic rays and nitrogen, presumably by increasing the
amount of atmospheric blocking (e.g., the ozone layer). I do not see how
this scenario achieves any of the above methods.

This won't change the 14C ratio in what was deposited, which is what you
are trying to explain, and carbon exchange between the atmosphere and ocean
surface waters is fairly rapid, so that washing it into the ocean does not
get rid of it for long.

Such a layer would allow freshwater organisms to survive, but would
suffocate the shallow marine fauna. Noah would need a lot of aquaria.

This does not explain the change in organisms through the stratigraphic
column nor the isotopic changes through the column between organisms from a
given depth.

Not if the isotopes reflect the environments where the animals were living
prior to the Flood. You need to develop an internally consistent model to
be credible.
The isotopic ratios of various kinds of meteorites, etc. are known, so it
woud be possible to estimate what sort of effect this model should have.
