Liquid Filled Spacecraft

So a random thought that has been wandering about in my brain over the last day or so, and my google foo has been too weak to find an offical answer. (I have found one, which sort of confirmed what I was thinking, but wanted to check....)

If you were to fill the cockpit of a spacecraft with a liquid that has a similar density to that of the crew's bodies, and included using a liquid respirant with similar gas carrying properties to perfluorocarbon, how would this effect the ability to survive extreme accelerations?

According to the wiki page on Liquid Breathing..

Quote:

Acceleration protection by liquid immersion is limited by the differential density of body tissues and immersion fluid, limiting the utility of this method to about 15 to 20 G. Extending acceleration protection beyond 20 G requires filling the lungs with fluid of density similar to water. An astronaut totally immersed in liquid, with liquid inside all body cavities, will feel little effect from extreme G forces because the forces on a liquid are distributed equally, and in all directions simultaneously. However effects will be felt because of density differences between different body tissues, so an upper acceleration limit still exists.

Is this correct, or would we be turned into a paste anyways? If correct, what would the upper limits of this be?
