Why not keep the Enve's and buy an inexpensive alloy wheelset for rainy days, wintertraining and when riding mountains like Shimano R501 wheels? I'm pretty sure you wont find faster wheels than the Enve's, even wheen going uphill, aero is more important than weight (to a certain degree), but the C24's are definitely not aero.
IMO C24 with the box section rim is an older technology. Pretty sure Shimano will upgrade the wheel at some point to something wider and more aero.
DA7800 vs. DA9000, well, there's a significant difference. The DA9000 according to several reviews shifts almost as well as the Di2 versions. But that doesn't give you any added performance. The Enve's do.
