Seems like it would be a bit of faff I think. If you’re going to go for the farm/industrial look with plastisol sheet I’d go for a box profile and fix them with tek screws as noted above. You can get fixings that go straight into timber so fixing onto a traditional timber kit shouldn’t be an issue.
Ive seen quite a few visitor centre/farm shop type buildings done in this style recently and providing the finishes are to a decent standard (windows doors etc.) it can look pretty decent.
