It doesn't really work that way.Re using your photo's - it's pretty standard to need a model release for anyone who can be identified in photo's.

If it's in a public space you can photograph anyone you want.
They can basically only object if they are pictured in such a way or used in a commercial way that might be negative for them (their image/status).

APS-C will never be on par with 135format because the sensor is bigger, it means the amount of pixels will be higher or that the pixels will be larger so a larger sensors will always be better.As for high ISO, we won't have to wait too long to see APS-C on par with FF.

However I think the APS-C has reach such a level that's good enough for almost anyone unless you print very large or need to use very high ISO.

And DOF is not as different as you might be led to believe. If I set both my Bronica ETRS 75mm lens and my Nikon 35mm camera with a 50mm lens on hyperfocal at f:22, the Nikon goes sharp from 1.9 m. to infinity. The Bronica gives me 2.15 m. to infinity. I guess the difference between FF and APS-C is about the same. Nothing to write home about.
About the difference in DOF, here you go.And DOF is not as different as you might be led to believe.

This the most important part.
The FA* 85mm on a 35mm camera and the DA* 55mm on a Pentax K10D.
Because the 55mm doesn't give the same angle of view as the FA* 85mm, we need to stand just a bit closer. The subject distance for the FA* 85mm is 10m and for the DA* 55mm 9.9m, with these distance the subject will be the same length on both photos.
With the distance given above and both wide open f/1.4 the;
DA* 55mm would have a DOF of 183.8 cm on the K10D
FA* 85mm would have a dof of 116.8 cm on 35mm film
So the DA* 55mm would not replace the FA* 85mm for his DOF

But by the time it gets over here $1 will probably equal £1 as is typical with Pentax prices (and probably those of other brands too)Quite pricey btw, the 645D is now ¥839,000 (~ US $9200 / 6350 GBP) and that's 40mp, how fast times change. ]

Don't know if it work with elements but in photoshop I simple great a new file with the pixel size that I want and simply copy past the photo in it.

It's noisier then the DA18-55 at least, the DA*16-50 use an SDM motor so you hardly hear that.
btw about noisy, the teacher at the photoclub explained the sound of the K10D shutter as a Kalashnikov, found it a nice comparison.
