The quantity calculation needs to take into account both the products. I fiddled around with the options/characteristics etc but that doesnt seem to work.

Options would work, if we could add counter to those, meaning the quantity of the options to be modified, that would work too. If you want to add both products in the cart in one go, I don't think that you'll be able to do it without using options.
