Requesting idea for a revisonable-esque webform functionality

Background:

I am aware that webforms being configurable entity and being a simple form in reality is not/does not qualify to be revisionable.

In my case, it is required that the webform be reviewed by potentially two levels of review before being available for use.

I'm implementing this functionality by using entity CRUD hooks, form alters and custom code for moderation forms. When an author creates the form it is automatically set as closed, accessibility to change form status restricted and appropriate moderation message is displayed to them.

Users with ability to moderate the form can then approve the form, which internally sets form status to Open and updates the respective status in my custom table. Once this is done the webform build will be updated such that users cannot add/edit/update elements to it without changing it to draft (which internally changes the form status to Closed).

Problem:

So when a form is already approved and live (linked to an article) to the end-users, making changes requires to close it for a brief period of time until it is reviewed and approved again.

I'm looking for suggestions on how this situation could be circumvented, where a possible faux-revison of the form can be reviewed and later updated over the original while the original form is still available to the end users. Some pointers on the possibility of achieving this or alternate method would be really helpful.
