I donĀ“t mean pixel skipping. I mean 4 connected pixels (photodiodes surfaces), which woul lead to reduced resolution, but higher natural dynamic range (flexibility).

That's what VPS is claimed to be.

The difference should be huge, like compact cameras photodiodes vs full frame camera photodiodes (with same res).

It's not nearly that simple. From a sensor designer:

Smaller pixels typically have lower read noise. One reason large pixels look less noisy is that they cannot detect high-frequency shot noise (or high-frequency detail either.)

See here for a comparison between two sensors one with 50% more pixels.
