Second store for clearance products

Hi all, so recently started a brand store for a business I represent and they’ve now asked about setting up a second. The intention is not to sell the exact same products but to sell of some of the extra clearance stock at a smaller margin. Purpose of not doing this via the first store is we don’t want the brand to be effected by this (aka some of the products are not fitting with the current range or same quality). Any advice how to do this or will I need to set up another seller account with a different domain etc?
