Modifying HMD Input in Blueprints?

I’m experimenting with a few different ideas that all involve adjusting the input of the HMD - for example, I’d like to restrict the maximum angle a player can turn their head so that when looking 90 degrees in one direction, the input is halved to 45 degrees, thereby only allowing the player viewing access to the front 180 degrees. I’ve tried modifying the Controller Yaw and Pitch inputs but it would appear that the HMD overrides these functions.

How do I modify HMD Input? Ideally in Blueprints, I’m not C++ savvy!

That seems like a very weird request that I would think would be likely to cause motion sickness(AAaaaaa… or what is it called actually had a very limited use for this and it kinda workd). But anyways how to do it. To actually override base hmd functions or rotation you would definitely have to dig in to c++. But you could get a close approximation without the benefits of timewarp and such by modifying the camera component of the pawn instead of the controller by introducing a halved inverted rotation.
