You won't find them on pegs, TLVs come in boxes!
I do wonder how retail shops stock them & display them over there though. I may have to Google this.
It's not like I gave it a lot of thought, but that's where I was at with the fire engine, too. With such a unique model, you'd think possibilities are endless.
I'm sure you'll come up with something really awesome.
As for the Tomicarama "style" thing, while it's not anything new, and it would be a departure from what we are used to seeing from Lamley, you are not stealing anything, at least not from me! I saw other collectors using dioramas to photograph hot wheels/minicars on the internet, so that's where I got the idea. You know TOMYTEC had such scenario in mind with Tomicarama as well.
Have you ever featured dioramas on Lamley? As you are aware, when I use that Shell gas station set, all my pics are close ups of the cars. With your photography, we should still be able to see the trademark white/gray background, so you'd think it will have its own unique look? It should look really cool, at least in my head it does.
