How safe is it to rig 4x4 kinos onto a cat pole stretched across a typical sized bedroom? Any suggestions to alternatives?

Not so safe with a long one fully extended. If you can rig a short one inside a window casement, you can get away with it. For anything over 8', the safer option is a 2"x4" wall spreader, or a pipe spreader.

I'll second 2x4 or pipe spreaders. With either, screw the wall plates onto pancakes to spread the pressure to a larger area. Make sure the 2x4s are oriented vertically for maximum strength. Make sure the wall is strong and ideally try to place them at studs or other support points; I heard about a crew popping bricks out of a wall.

 

Another option that is better than polecat wall-to-wall is to put two polecats floor-to-cieling on opposite sides of the room, then use cheeseborroughs to make a speedrail crossbeam between them. This will depend on what the frame is and how good your art department is.

Also, you might look into removing the back plates and screwing the kino housings directly into the ceiling. Its not so hard to patch up the little screw holes.
