Came very close, Spock to ECS and PSI tuning. Both reassured there would be no issues, but there was still a nagging doubt that these lifting points ( where the bungs fit) are designed to be lifted on all 4 points at once, hence sharing the weight/load.
There were some cases, particularly TT where lifting with a trolley jack on one point bent the floor pan.
I didn't want to risk it, so bailed out the idea.
I'm using similar.
On the 8p you don't lift on the seam edge but either side so need the deep one to ensure clearance.
On the newer 8v you lift on the reinforced seam edge so need the shallow one.
Ive also made up a lifting block like Johns wooden one, but in Ally , with a rubber top, but haven't had need to use it yet, as my lifting area is not totally flat.
Plopped6-years on and still using the same on mine and others, Paul:

RS3 at the front, TT to the left, and A1 to the right; no worries...
