Using multisite with woocommerce and pull products from 1 site on all sites

I am running Woocommerce on a wordpress multisite setup and the network is set up to use 2 different domains. For example:

site-one.com
site-two.com

Both sites need to have the exact same products on each and including variations there are over 10,000 products.

I currently use a plugin called WooMultistore to sync any changes products to both sites:

https://woomultistore.com/

The problem with this is that I now have a database with 2 lots of 10,000 products which just seems silly and wasteful and it also doing any kind of bulk editing cripples both sites.

I’m trying to develop a way so that site-two.com pulls its products from site-one.com and have had partial success with using pre_get_posts and telling site-two.com to use site-one.com posts and postmeta tables. This fails at the point of being able to add the products to the basket on site-two.com and so I’m at an impasse with it now.

I started a thread on WordPress stackoverflow:
