Is there an open pollinated selection of candyland tomato?

Looking for a smaller but yet still tasty version of Matt's Wild Cherry tomato. Came across Candyland but discovered that it was an F1 hybrid. So I wondered if anyone is working on making this into a stable, o.p. variety. I know that folks are trying to accomplish that with Sungold cherry tomatoes, but we prefer the more acidic bite of the Matt's Wild Cherry to most any other cherry tomato, even if its 12'+ vines threaten to take over the garden. Maybe Candyland fits that flavor profile but on a more well behaved plant?
