I like the swap idea! 52 swappers with 7 colors each or 31 swappers with 12 colors each would make the set. With 52 swappers you’d need to buy 7 one yard cuts each, or with 31 swappers you’d buy twelve 2/3 yard cuts. The 365 squares would make a quilt finishing 76.5 by 99 (or so - hard to make it even).
