I've thought alot about making those armours, especially the lanister ones. The only big issues though is how you would get all those small ornate details, which honestly, makes up 80 percent of the armours beauty(should you take it off you're left with a rather simple and standard armour set). You could add them in if you took the time and did it carefully but It would look quite bad in lower rev with the high polycount. I guess you could try having it textured on there but again, will not look great on lower revs regardless. It seems to be a task for a higher revision which idk if maximax does / likes
