Not really, because investors would typically be using Interactive Brokers for this path. And that usually ends up being a US$10/month fixed price.
Sure, if you set a boundary condition that investors use Interactive Brokers for this path, and assuming that they only do their weekly/monthly DCA and do not do other trades as well that exceeds the minimum US$10/month, then yes you can add the dividend yields on the months that the DCA up have not vested to the DCA blind's portfolio. But note that a boundary condition has been applied (that may well be applicable for most investors).
