K-Member Removal with Engine in Place?

A spin off from my other thread Odd Suspension Issue "Fixed" Itself

I'm investigating options for repair of the broken LCA pivot sleeve weld in the K-Member on our '73 Dart Custom 225/TF904, and was wondering if it's feasible to pull the K-member while leaving the engine in the car (using appropriate ground support)? Seems like it could work...

The scope of this job has already ballooned dramatically from what I had hoped, and I'd rather not add an engine pull at this time.

I guess another option might be for me to attempt to fix the broken joint in place. I've done a small amount of welding with arc/stick & oxy/acetylene decades ago, and have been considering getting a welder for this and many other projects.

Mopar sure didn't seem to give this LCA mounting point much thought, considering the job it has to do.

Input appreciated, thanks.
They make supports mostly for front wheel dive cars that would sit on the fender aprons and the engine
can be supported by chains attached to it like when one pulls an engine. Parts stores or a rental place
might rent these. It would probably be a lot of money to purchase one of these for a one time use.
Or one can improvise with wood blocks and a piece of square tubing.
