Yes it is possible to modify the LDS air file or copy it to another plane. But you are asking for MAJOR problems. The CS 767 has very different design points than the LDS 767. You may experience bouncing, floating planes and a host of other problems. If you want a excellent flight model than use the LDS 767 files you bought.Bob
