Basically, all you will need is a second matching lead screw, motor, mount and coupler. I recommend buying two leadscrews together, as I had a hard time finding one that matched the ender 5 leadscrew.

 

I had several ideas to replace the floppy bed assembly for a dual leadscrew solution. After a few complicated ideas, I felt I'd be able to get a good result with the existing hardware if I just added a leadscrew without the linear rails.
Seems to work great so far, even now with a much-upgraded motion system thrashing about.

The bed support and the leadscrew bracket are fastened with M4 screws tapped into the plate. This is the most rigid solution. I can't find the source for the bed support, but you might find you don't need it - I already had them fitted so I'll keep them on.

The T8 leadscrew nuts are at exactly the same height, to make alignment easy.

Printing:  I didn't use supports but used bridging at the underside of the T8 nut. This is why the holes have a .2mm layer closing them off. Just ram a screw driver or drill bit through after printing.
