NO. The bolts are too small and highly stressed.

and you don't want to finish your ride like this


I broke the first bolt shrinking from 185 to 154 pounds over 3415 miles.

I replaced the bolts with new ones having 20% higher yield strength, and broke the second front bolt in 1690 miles when I was down to 140.

Having the saddle farther forward would put less stress on the front bolt, although moving the saddle back is the whole point to a long setback seatpost.
