Hi,
A lot of things would be great and we have a lot of things in our TODO list.
The refactoring of the product page in the backend s one of these points and we will work on it quite soon using the work made in HikaMarket to improve the product edition.
About your requirement, your idea. I want to say that, it could be interesting and it is something which can be implemented using an external plugin.
You are free to create your plugins to add your features, the HikaShop developer documentation list all triggers and with the next release (thanks to mass-actions) you will be able to do a lot of things without coding at all.
Regards,
