Replace a Front Frame Rail - How Much Trouble?

I may be off base, but my thought was to level the car as level as I could get it using some leveling screws like shown in the picture (used for scaffolding), maybe with a steel tubing framework that would let me get the car level but leave space to remove the rail. I also thought I'd make some sort of locating jig that would allow me to get the new shock tower back in the same place as the original one. I expect that the front sheet metal will have to come off, the engine will have to come out, the complete front suspension will have to come out and the K-frame will have to be removed. The driver's side inner fender will also have to be removed. This all came about because I wanted to rebuild the front suspension.

Removing and replacing a frame rail was not on the agenda and actually it's very intimidating to me. I planned on learning a lot with this project but didn't really plan on going that deep into it. On the bright side, I intended to remove the front suspension anyway so I could rebuild it and make it look nice. This will also give me a chance to blast the K-frame and repaint it as well as make a minor repair to the driver side inner fender. An engine refresh would probably also be smart at this point.
