Transparency dial in Immersive mode

In Progressive mode, you can turn the digital crown which will reveal your environment by limiting/expanding the field of view of your Immersive scene.

I'm trying to create a different sort of behavior where your Immersive scene remains in 360 mode but adjusting a dial (doesn't have to be the crown, it could be an in-app dial/slider) adjusts the transparency of the scene.

My users aren't quite satisfied with the native features that help ensure you aren't about to run into a wall or furniture and want a way of quickly adjusting the transparency on the fly.

Is that possible?
