I did a little testing on the rubber bumpers without the spring installed and sure enough that thing compresses to the point where I had to stop or I thought it would split. I don't know how you would calculate for that with travel. But if you hit it often it would be destroyed.

Measurements:
The Lower A arm pivot point to balljoint center is 12.87" and it is 4 deg. down on the outside at ride height.

The lower A arm pivot point to shock mount is 7.87".

The shock it presently at 15 deg. with the angle between the A arm and the shock = 19 deg.

I believe the intention would be to relocate the upper mount and use shock QA1 4855B.
It is 10.130 compressed and 14.25 extended. Then subtracting whatever for the bump stop that is about 1.25".

The other measurements are:
1. I would like ride height to be at 27" from ground to lip of the fender.

2. At just about 25.5" to lip of the fender the tire is just about as high as it can go without rubbing. That is without a load on the tire with spring removed. That may bring it to 25" with weight on the tire. But then there's that bump stop.

3. At 30" from lip of fender to the ground the ball joints hit.

So which way do you figure it from? Do you set it at from the bottom up, say 29.5", and so it doesn't hit the ball joints? Or do you set it from the top most compression and and let the extra shock on the down side and then maybe add a droop stop under an upper A arm so you don't damage the ball joints.
