has anybody done this yet

This would be a heck of a lot of work but I've thought about it. As long as it's not a column shift, you could shorten the column jacket, custom make a support bushing "up there" under the dash at the bottom of where you cut off the column jacket, ..............and run a U joint on a new shaft from under the dash.......out through the floor plate. You could "tweek" the column slightly to point the bottom shaft outboard a slight amount, then run the second shaft down and through a second bushing at the floor plate. You might have to oblong the holes and move it, or maybe just mount your bushing plate offset. You could keep the factory joint or use something else.

This came to me, LOL when I was dreaming of a hemi swap......never gonna happen
