OME heavy duty leaf pack plus another leaf??

So I know the 0ME heavy duty leaf pack gives about 2.75 inches of lift and it’s good for 668 consistent pounds!!!

Had anyone ever got this leaf pack but put another extra overload leaf on them so there two times heavy duty? So 2 overload leafs!! If my calculations are correct an extra leaf in the pack should give me an additional half inch of list and another 330 pounds of weight capacity right? So I should be over 3 inches of lift and about 900 pounds capacity right? I want to make them extra heavy duty.
Thanks guys

 

I've heard this has been done. A guy on a Facebook group for four wheel campers mentioned it the other day and said it was pretty common. I may look into this too since my Dobinsons springs showed up rusty.
