Can I make Camera ProjectionMode mask?

Hi! I trying to understand how to specify in what Camera ProjectionMode will each object appear on the screen. For example set all scene to OrthographicMode but one selected StaticMesh will be still in PerspectiveMode. Also I need ability to make this selected object render as it looks from different camera. Here image to make idea more understandable:

All objects are projected to Camera A (PlayerCamera) screenspace. Objects labeled by “X” are in OrthographicMode but green “R” object is projected to Camera A screenspace as it looks in PerspectiveMode from B camera point of view. Do you think is it possible? If you have any thoughts about where I should start - please comment! Thanks.
