Shopify App - Customized Bundle App

We are looking for a customized bundle app for our Shopify store. We researched and tried dozens of bundle apps, but none of them fullfills all our needs. Please find below the functional and ux requirements for this bundle app:

• The app should show between 3-5 products in one line at the main product page (see example picture attached)
• The price of all individual products should be added up and then be discounted to a bundle price (line item discount)
• The app should show a customizable title and a customizable text for the product
• The first bundle item (which is the same as the product page above) should change if the visitor changes the variation on top
• The app should be able to show variations of the bundled items and make it selectable (for example bundle item 2 is an extra lens -> then the customer should be able to choose the variation color of the bundle item)
• The images of the variation should change dynamically
• 2x the same variation in the bundle should be possible
• The bundle item should be able to be placed in the checkout as well as an off-cart drawer (we use the app Slide Cart Drawer- Cart Upsell)
• When one variation is not on stock -> the bundle should be greyed out

Please don’t hesitate to ask more about this project if you have any questions.
Thanks
Chris
