Auto to manual swap

I'm daydreaming again...a few questions on my mind:
Has anyone done a T56 swap yet? Is it that much better than a TKO 5spd?

What are the hard parts of this job? Is any welding (mounts, floor, etc.) required?

Can this job be realistically done with ramps/jackstands? I have pulled/installed my A904 without a lift...but I can imagine that some of the aspects of this job might be difficult from the supine position.

Is this something that an average mechanic should even think about?
