I have used rivet nuts only a handful of times hope i'm getting ready to use some in one of my boat projects right now. I thought about your post for a little while, and then I thought I might mention this.
Have you considered using a stainless steel counter sunk rivet nut.
Obviously you would need to dimple the hole so that the counter sunk head or rim would sit flush. But I don't think that would be a complex dimple die to make.

The upper front fender channel area I'm working on is open at both ends and can have water enter within from the cowl end drains and externally from splash past the fender liner. Rust may have started along the box channel's lower edge under trapped oak tree debris that entered from the cowl drain. Those trees are gone now. Much of the area is still intact and retains the LPS-3 wax I sprayed on accessible surfaces many years (decades?) ago. They made poor decisions on water sealing and trapping in some areas, like this
and the rear fender holes for the snap-on trim sealed by foam that deteriorated. The rust-through that resulted was excessively expensive to repair unless DIY. The dealer quoted me $3600.
I plan to caulk the upper edge and leave the bottom edge unsealed for drainage. It sits in a channel in the plastic fender liner, or will if I get the difficult fit correct. The 18 ga steel patch is too difficult to form to
a tight flush fit to the curved surfaces, the small standoff of the rivnut heads will help.
I made a sheet metal screw and rivet head countersinking punch for my Roper Whitney No. 5 Junior hand punch (clone) that worked well but needs to be harder because the die expanded and jammed in the threads. Away from edges a two part screw together dimpler would be better. I made a similar wrench tightened grommet setting punch and die for installing them on hanging
tarps.
Though the vehicle is a Honda the body is a Land Rover design from a brief joint venture.

Honda had been making a similar AWD SUV for a decade, the Civic Wagovan,
which was so ugly it could be mistaken for a Citroen. They were more than ready for a body style that would sell.
I really like the combination of Honda reliability and Land Rover practicality, which faded as Honda stylists put their marks on later models. The built-in folding table:

Below it is a water-tight tub, the kitchen sink. A cargo compartment 12V outlet runs my small DC freezer. The seats fold flat to sleep on. It has the large Land Rover windows to better view the hungry lions circling outside.
I didn't mention looks or excitement, it's what Clark Kent would drive to
stay invisible. The thrill is when I'm in control on ice and everyone else isn't. The only addition I've made was a backup camera mount through the
spare tire center.
