Hello,
I'm afraid that I can't say yes.
Because an order is something fixed in the past ; the products of the order can evolve, change.
It is also possible that the products do not exist anymore in your database.
But HikaShop keep some information at the moment when the ordre is made, like the name or the price. Unfortunately, it cannot save all data of products.
That's why, if the weight is added, it will be an information read from the database and it could be an incorrect information. HikaShop would not have the possibility to know it and warn the user.
That's how it is not something that would be integrated into the HIkaShop core but that's something that you could add in your end thanks to overrides.
