drop member and kp notch on 4wd frame?

[blazerboy72]

I have finally finished my unexpected project so I can get back on to my blazer but now im not sure which direction I want to go. It is an original 71 2wd. The problem is I want it LOW but I dont want to cut the original frame in case I ever want to put it back to stock. So could I use a 4wd frame with one of porters drop members, a 4link and a kp notch? Im sure this is a stupid question and has been answered a thousand times but I just wanted to make sure before I started buying parts.
