Ouch
My door sags also and you may have the same problem: The hinge pin is not juct 'compressed', it is actually rusted out and collapsed. I cant seem to be able to drive it out because it is broken inside the hinge.
So I did what you are thinking about and put a tight fitting stainless bolt thru the center. Its better but still sags a bit.
I believe that to get the old pin out I may have to fabricate a puller like the manual shows or get a right angle drill and try to drill the pin out from the bottom.
BTW This is a good reason to keep the plastic caps in the top end of the hinge pins.
