Hello,
I'm afraid that HikaShop is not really concerned by your request since it's related to the Joomla routing system.
Joomla needs a "menu" to know which component is used and which component it needs to load and call.
Otherwise, you'll need a routing component (also called a SEF component) which will do that work for you.
