There are some that are already using the 4.2 Photosphere camera, simple, do a Nandroid, then flash the SK 4.2 package, then give it a shot and see if you like it and have any issues. If you do get lag or issues, then simply Nandroid back, problem solved. According to CMB hs next release will be 4.2 so your wish might just be his next command.
***WARNING*** This will only work on deodexed 4.1+ rom', you can also simply extract the camera and flash that also.
