In other words, just using it as a long-travel single shock application?
Don't see why it wouldn't work, unless the shock you choose has some clearance issues with a large body, or can't be mounted with the shaft down.
As always, trial fitting is your friend, but in this case, that's an expensive experiment, so I can see why you're asking around first.
Don't know for sure without looking at it, but if you don't get an answer here I can check when I get back to the new shop on Friday and (if I have the chance) can check out an installed set to see what I think.
You could call in with your question of course, but I doubt you'll get a definitive answer this week with all that's going on.
If you do call in just to see though, check with Johnny as he's dealt with them the longest. Might know off the top of his head.
Good luck. Be interested to see what others have to say. I bet there's someone here running that orientation.
