Is it possible to programmatically send custom camera poses to oculus sdk

My goal:

My goal is to get a 360 picture of a third party app. I know about Unreal Engine 4 (UE4) and Unity 360° Video Capture Software (surrealcapture.com). However, this app was not built in either. So, I want to take 6 photos and stitch them into a cubemap. 

How I am thinking of doing it:

I am wondering if it's possible to intercept the headsets actual pose and send a specifc pose until I am able to screen capture it. Then, rotate and do it again.

Would something like this be possible?
