I know this may or may not be rejected, but I think I have some ideas on how to make it work.
1. One idea is to make a new extension for VR:
How this would work is that it would give you a new set of blocks and give a “?” button for a tutorial on how this would work and how to make a
cardboard headset. This has a lower chance of working since scratch is for beginners, but who knows?
2. Make a VR game that works like Scratch, but VR related:
Yeah. It's basically in the name.

1.7 3D Scratch
This block, and others, could be used with a z-axis in the project stage to make it easier to create 3D projects. But, Scratch is a language that is designed to be as easy as possible for beginners to learn. Adding 3D features would make the language more difficult for beginners to understand, and a 3D engine is not exactly the purpose of Scratch. This suggestion also includes the possibility for virtual-reality features in Scratch, or “Scratch VR.” A lot of the same difficulties come up.

For those who are interested, it may be worth checking out Beetle Blocks or CreatiCode. They are block-based programming languages similar to the Scratch editor, but with 3D features. There is another similar program to Scratch that contains block programming with 3D features, called Starlogo TNG. You can also try Alice; it is not exactly like Scratch, but has some similar features.

It is rejected (meaning it would not be able to be added for the reasons below)

Alright, two things:

• As others have stated, this would technically be rejected, as VR is 3D, and 3D Scratch is rejected.
  
• This would cost a lot of money that the Scratch Team does not have
