Cotswold is not just into high-end, they are the #1 source for retro Joe stuff. Most of the stuff they promote is Adventure Team style stuff, they just carry the other 1:6 stuff as well. This is the website: https://www.gijoeelite.com/
Their Elite Brigade brand is where all the AT-inspired stuff is. They had made so much stuff in recent years.
There is a big market. Estrela is making Falcon sets again, Geyperman is making stuff and Action Man is back as well. Strike while the iron is hot!
