Seems to be the measuring stick if we're talking about a series. Granted the special effects needed for WOT would greatly surpass anything that they would need but if they can't even pull off the Direwolves relatively well, what hope would there be for anything that's on a bigger scale than that?

Not saying it can't be done, but I think a wait and see approach along with a looong pre-production period (if it ever happens) would be best for WOT.
