Mirror online store in the affiliate program

As you know, many online stores offer affiliate programs that work according to a simple scheme: you place links to IM or individual goods, and if a visitor follows this special link with the code and buys the goods, then you will be deducted from the amount of the purchase 2-3 %

But there is another scheme. A full-fledged online store with a catalog of goods, their description, basket and order form. But only the assortment and prices are coordinated with another online store, to which received orders are simply transferred, and from them, of course, interest already goes.

I want to ask the experts and owners of online stores, how much such a scheme is possible in terms of profitability. That is, is it really possible for your IM, working according to such a scheme, to bring at least some kind of income? Particularly interested in this issue against the background of reducing the effectiveness and popularity of affiliate programs as marketing tools.
