Hello, Dufink, thank you for your answer.
My initial thought was also to make this happen with rules but I soon realized that I needed some extra functionality that rules couldn't give me. Like keeping parts of the add to cart form still accessible and printing out a message in it's own div inside the form. Maybe it's possible to do however and it's just my understanding of rules that's lacking.
My second plan was to simply hide certain elements with jQuery, but thankfully I didn't have to do that either.
What I in the end managed to do, with the help of a colleague of mine, was to utilize the "commerce_cart_attributes_refresh_alter" function to check the boolean(That controls if the product is available for private customers.) for the ajax-loaded product variation, then double check that value with an array of viable roles.
It's not the most beautiful of solutions but It's a one-time set thing that won't need any altering in any foreseeable future so it works fine for my needs.
Posting code in case anyone else have need for a similar thing.

/**
* Implements hook_form_alter().

* Alter the Commerce 'Add to Cart' form.

$default_product = $form['product_id']['#default_value'];
//Load the product.
$product = commerce_product_load($default_product);
