Want to upgrade screen

Yes you can you can replace the LCD you speak of with any and all of the LCDs you mention. The LVDS/video cable is the sane for all of them, see for compatibility list of the cable. There is more information on the compatibility of the screen here and here. You will need to reset your SMC and PRAM after the exchange. Instructions for doing that are here and here. Resetting the PRAM should take care of color and resolution changes.

To address the question in your last comment: Apple handles the cameras through USB emulation. The connector/socket for the camera is just a funny looking USB port. As long as the connector on the wire fits in the socket it will work as originally intended.

Based on that comment I think you are really wanting to exchange entire upper assembles between the 2 laptops, which is slightly different than your original question and requires a number of different considerations to be addressed than those posed initially ie: Are the hinges the same and are they going to line up and mount the same?, Are the wires for the camera and wireless going to be long enough and mount the same on the logic board? etc....

If the hinges are the same but mount slightly different, this will not work. etc...

To exchange entire upper assemblies you will need to make sure the hinges will align, mount the same and are the same distance from the upper edge from the top of the lower case. You will need to verify that the camera and wifi cables are the same length and connect the same. Since you have booth laptops there you are the most qualified person to determine these things.
