To be honest for 30 grand I would want it out of metal not fiberglass.
Challenge to all the tool heads out there, how much do you think it would cost to make a metal replica of the GoT throne, I personally would get metal from the scrap heap. then melt it down ( I am not a gearhead so I don´'t know what kind of metal or if this is even possible ).
The sheer mass of an all-metal throne would make moving it prohibitive, requiring a forklift at least.
Not to mention the number it would do on whatever floor you set it on.
