How can I delete orphaned Product Displays? Using Commerce Kickstart 2.

We have a number of orphaned nodes we would like to delete, ie Product Displays which reference no Product Variation.

I created a View with VBO which shows me these nodes, but unfortunately, it throws an error when attempting to delete since each orphan is missing certain required fields.

Is there a way to -force- VBO to delete these nodes (bypass the form validation for each delete?)

Or... is there a SQL Query you can recommend which will do the same thing (hopefully safely)?
Perhaps a PHP script that mimics creation of that View list and then utilizes a node_delete_multiple().  Granted, you will want to test this out very carefully before actually using a method like this.  

That said, an Entity Field Query coupled with a node_delete_multiple() may be what you're looking for.  Again, test very well, look at the DB after a test run, see that everything you want deleted is.
