To manage something like a Lexicon reverb properly you would run your source into a mixer and then run a send from the mixer to each effect unit you want to use. Then the stereo returns come back and get mixed with your dry signal, which would generally also have its own speaker in a W/D/W rig. Rack gear is just an entirely different world of routing if you're doing it the way the manufacturer intends.
Preserving stereo spread is pretty important to me. I bought a line mixer with two independent stereo aux sends so I can take, let’s say, a stereo multi tap delay in parallel with a mono dry preamp out, run a Dimension-y chorus in the first aux, and a stereo input reverb in the second. A delay tap audible on the left would pull the reverb image to the left. If the manufacturers have stereo input algorithms, this is what is intended to be possible.
