Reality is our 16MP sensor are just 4MP full color sensor. Interpolation give the 16MP. But this is half a marketing claim. Technically your full HD monitor is 2MP full pixels but is able to display 6MP, 1/3 red, 1/3 blue, 1/3 green. This is used by computers to increase actual resolution of text for example. The computer know your model of screen, how the red/green/blue sub pixel are spread and draw the shape of fonts more accurately by only using the sub pixel that really matches the global shape.
So you sensor is using interpolation to try to simulate 16MP full color matrix. But this is by far not of same quality as real full 16MP image. You can get a sense of that by getting say a 645Z or D800 shoot, resize it to 16MP and look at it at 100%. Your results will be better with 645Z or D800 even through you kept final size to 16MP.
So our 16MP is say something is between 4MP and 16MP... Maybe 8MP or something like that. Difficult to say because it also depend of the patterns it need to reproduce. For some use case the interpolation fail short (like when you have moire) in other cases it work quite well.
So to go back to getting more resolution, I'am affraid by moving full pixel on a 16MP sensor that you'll just get full color 16MP shoot. That will be already quite better but not the max you can achieve.
If you move not full pixel size but something different like 1/2 pixel size and 4 shoots, you can somehow get an interpolated 64MP shoot. They may not be worth really 96MP but for sure they give you more than you current 16MP sensor... Maybe get you at same level as current 645Z or something. Not that bad.
And as for 645Z, nothing prevent it to interpolate to 200MP this way. It has already been done by other camera maker.
Biggest issue for me: it really work only if you use a tripod.
