As a replacement for the second Ori product, I was going to suggest a bagman support from carradice:

But they've changed them now, and I don't think the new one makes any sense with a folder

(like the wheel kit: I've never really rolled my Mezzo, and I took it on a shopping trip a couple of days ago - department stores so lots of carrying - and my lower back hurts now
)
