Custom-created or personalized products with Craft Commerce?
I don't think there is a plugin for this, so the only way to solve this would be to build the plugin for this yourself, if you have the skills or resources for this. It could be solved by creating a purchasable with (optional) relations to all the products needed, checking the stock of those products on adding it to the basket, and/or on checkout.

What I would start with, though, is creating an issue on Commerce's Github, to see if others have a need for this and hope that Pixel &amp; Tonic's crew will do it for you ;)
