Hi,
Well, it depends 
It depends what you want.
If the products have options or characteristics or custom fields, I would say no, as it would require a lot of development as the javascript code to handle these isn't made to support that.
If the products don't have these, then you could try to use
www.regularlabs.com/extensions/componentsanywhere
to have both product pages inside a Joomla article. Or you could also use instead the content tag plugin instead of the components anywhere :
www.hikashop.com/support/documentation/1...-product-insert.html
Alternatively, you could also create a menu item of the type HikaShop comparison page, and enter the id of both products in the menu item settings.
Then, you would have both next to one other on the menu item page, with one row per custom product field (great to be able to compare 2 products' specifications together).
