Reading something in the Mantic games thread made me wonder why GW don't do this?

Seeing as they already have very nice models in 3 up scale, could they not release some of them as FW resin casts?

I know selling between the divisions seems to be some huge obstacle, but those 3 ups are probably just shoved in the back of a drawer somewhere after they've been used.

At the very least they could offer some of them as one of a kind prizes at some point.
