Not that I think we could do anything in this comp, we are unlucky geographically to be in the South group, Kent and Sussex are the two best teams in the country in t20.
In fairness though, that would have been said about us in the early 2010s.
First losing Dimi, Briggs and Macca. Then Carberry, Adams and Ervine reaching their sell-by dates. Benks chucking Wheater out didn't help either (the only keeper we've ever had, other than Pothas, who can actually bat in t20). We've never really replaced any of them, although Will Smith did a sterling job with the ball for a few years. Vince and Dawson have largely carried our t20 team for about four years now. And no obvious signs from the youngsters/reserves this season that they could do a job for us going forward in t20 - save maybe for the odd bright spark from Holland.
