Idea for an animated wallpaper ... feasible?

I have an idea for one, but I don't even know if it's physically possible to make.

I'd love to have an animated wallpaper of the Ice Hockey NES game. You know, this one:



However, I'd like to put a Bruins logo at center ice, and change the team colors to Black & Gold, and probably red & blue (for the dreaded Habs).

Since the size of a wallpaper is 960x854, I'm not even sure how that would work, cause that screenshot of half the ice is about that size.

So I just wondering if this is a feasible idea before I go about finding someone to do it. Thanks!
