WoW...Talk about over thinking of a simple job....
I guess if you have a fancy hoist and a welder and all the materials needed it would be easy to pull off such a indepth plan....

Myself I choose the simple route....I've done over a dozen cars in the last 15 years using the base of my engine stand, some towels, 2X4's and duct tape....

With the rear axle in the car, I simple raise the front end, slip the complete engine/trans/suspension in then lower the car using an engine hoist....
It's a one man job that take about 20mins...
