Disk brakes from salvage.?

i have a 69 Chevy nova. i have just redone the front and rear drum brakes. but I'm thinking this on a hypothetical sense / maybe hope to do this. But would it be possible to go to a salvage yard and find a vehicle with front and rear disk breaks, just taking the whole backing plate. the whole assembly (all 4 of them). Then the master cylinder, distribution block, and power brake booster. Then mounting that backing plate to my nova (not sure how to do that but i'm sure there is a way). running the brake lines to the new distribution block and master cylinder. what are your thoughts.
