This a well known technique since the XIX century.
Just you need a longitudinal plating (or curtain) to avoid the image circle from one lens exposing the negative area of the other lens.
If your subject is static you can use the cha-cha method, this is moving the tripod towards one side to take a second shot.
The 1-30 rule: The lateral separation between the two shots should be around 1/30 of the camera to subject distance.
For displaying the capture there are several ways, this is the easiest:

The shift movement of the camera would be enough to take the two shots ...if the amount of shift can reach 1/30 of the subject distance, but you can also just move the tripod. You can shot a bit wider than what you will show to have some room to align the images as you want.
