would a FG inlet manifold fit on a BA? They look they same plus the fg one is plastic = lightweight and looks to be bigger?

I think it will fit, but I'm pretty sure the ECU will crack the sads, I'm not sure if a flash tune will fix that issue though. Also I'm not sure that there'd be any advantage, BA throttle bodys are still pretty big, and the manifolds flow very well, just look how much power the XR6T and F6 guys are getting with them.
