conditional limit on cart by weight

Hi, I would like to put a limit on purchases for a specific product such that if customers order product A, they have to order at least 10kg of the rest of the other items but if product A is not in the cart, there is no limit on the order weight. Does anyone know how I can implement this?

I have been going through the apps available on order limits but nothing allows me to have a condition like I need. 

Hope someone could help. Thanks in advance.
