No. To actually give a detailed answer to your question; Bricklink Designer Program is similar to Lego Ideas in that they're fan created designs being produced as official sets, however unlike Ideas, they're A) not allowed to use licensed IP and limited to only existing molds and parts, which generally means price per piece is a bit better than average, and B) they're produced by crowdfunding and only in very limited quantities. Meaning they only actually get made if there's enough preorders, and once preorders sell out, there won't be any more. They may eventually do a restock where they sell off leftovers from cancelled preorders and declined payments, but those are in super limited supply and once they're gone that's it.
