There is @sugarsteem project that never got off the ground. It started by @theuxyeti as an effort to add improvements to Steemit but that fell of def ears from Steemit Inc. It then changed directions and was going to be a new Dapp as an alternate to Steemit but way better user interface designed by an experienced UX guy. The problem is that it didn't get the dev support to get off the ground so it never happened.

If the Dev and the UX folks can come together, then you have something, but it seems like the devs like to have their interface boring and sterile.

If you are looking to make a difference, then get the right people together to host and launch @sugarsteem project.
