I'll give you my thoughts.

1) You will have to remove both the front bumper and fenders to get to the mounting bolts and remove the lights.

2) You will need to code the FRM module to deactivate the bulb check on the AEs.

3) I believe you have to code "something else" to get the adaptive portion of the lights to work.

From what I've read, just swapping the lights, the headlamps will work, but the self leveling and adaptive portion may not without some coding.
