Hell yes it could work! FG needs plenty of terrain to block line of sight, and multi-level is always a plus. Think of all those ruined cities Conan finds himself wandering through, and you'll be right on the mark! Pillars, walls, columns, ruined temples, collapsed buildings...
I'm seriously considering buying back in to Copplestone Barbarica and your line of stuff, and this will only add fuel to the fire!
