Variable Bundled Product

Hello, I am stuck with the following problem:

I have A bundled product “PBundle” which consists of 5 simple products. Now I would like to sell this Bundled product in different sizes

• single PBundle
• Box of 20 PBundle
• Box of 30 PBundle

Each size should be freely orderable, i.E. so you can say I want 3 x 30 Box of PBundle as well as 5 x single Packets in the cart.
I have managed this by creating 3 different Product Bundles.

But now I want ALL of those 3 products to show up on one product page and select from a dropdown which size I am Ordering (similar to a variable product).

Any ideas on this?

Thank you.
