To fill the LOX tank before the vehicle topples would take an opening about the same size as the diameter.  I don't think there's any practical way to do that.  You only have a single handful of seconds to get the job done.

For GW Johnson re #451

Thank you for considering the question of admitting water to the vehicle to stabilize it while keeping it afloat.

It appears that trying to fill the oxygen tank, or even just admit ** some ** water into the tank is unlikely to succeed,

The rate of release of air inside the body of the vehicle would be a factor, if an opening at the top of the vehicle were provided.

I'm back from looking at several video's, and there was no evidence of an opening at the top of Starship in any of them.

There ** is ** another strategy that might allow the Starship to survive rotation from vertical to horizontal at landing... If the vehicle had some horizontal velocity, then as the ship's stern enters the water, it would drag, and the ship would tip in the direction of movement. If the direction were controlled so that the back of the ship hits the water, that part of the ship would be least elevated in temperature.
