8-3/4 shock plates swap

I was touring the Chrysler Carlisle Nats A body section and noticed the 70 darts lined up in a row. I also noticed that some darts were higher in the rear than others. Thought SS springs but as no one was with their cars and couldn't ask questions I did notice one difference.
In Pic 1 this car had a stock appearing rear shock plate
In Pic 2 this car had a lowered shock bolt location
Searching the web I found that a 70 E body has a shock plate as in pic 2
Just wondering if using the E body plate in an A body and with re-arched springs (or rebops with 1 or 2" lift built in) would work to raise up the rear
I did like the stance of car in Pic #2 > raised a little but not a lot
Any thoughts
