Mix between compsite and products bundle

HI

I need a plugin ( or modify composite or chained producs) that modify the quantity of a list of products, depending of one variable.

For example, I have the main prodcut:
-Room painting (m2)
and these products (chained or composie)
-Paint bucket
-Varnish bucket

And the variable depende of the units of the main products

Let’s suppose that for every square meter I need 0.5 pain bucket and 0.3 varnish bucket.
The formula will be: ceiling(0.5 * m2) for pain bucket and ceiling(0.3 * m2) for varnish

So, if I insert 3 units for Room painting, the quantity must be:
-Paint bucket 2
-Varnish bucket 1

and then i can add to cart the two products (or one if is a bundle product)

Any solution please?

I will be appreciate any solution

thanks
