Phil, now you've got me worried about ever getting a flat on the road with my DD, Ram 5500. Didn't come with a jack so I got a bottle jack / stand combo that I checked would fit and lift it, but that was without a flat tire. Now I see your true genius.
I totally agree with @Mark W about the dangers of lifting especially with a Hi Lift jack. The JeedNeeds DLA and spiking the base does do a lot for making sure (maybe helping is better) that it won't slip off. For the people that haven't seen a Hi Lift handle flip up (that's probably someone...
I have a Slee rear and a Hefty (I think) front bumper. With my lift, I need a 60" Hi-Lift to change a tire. That's kind of scary getting that high so I use a (sorry for the profanity) JeepsNeeds shackle adapter to be sure it won't slip off.
I gave away my FSM away with my 3FE but I think you may have to remove the shroud and fan. Then when you remove the cross member and support the tranny, you'd be able to lower it enough to get to those bolts. I didn't hear you mention the torque converter bolts.
I didn't see anybody suggest it so I'll say to be sure to do the heater hose while the engine is out. Also, check inside the pistons for silica packs before you bolt on the oil pan. I'm embarrassed to say how I know that.
