I don't really understand what you're talking about.
I do get what you're asking for, but I'm really not a fan of perfectly uniform pieces, and more than that can't understand how such a trivial part of the cube would matter for speedcubing.
If a cube came out that looked like the older C4Y DIYs but performed and felt better than by main, I'd happily use it, even though I don't like the aesthetic. So my suggestion, respectfully, is to get a Gans Air and get over it.
EDIT: I have, however, been wondering pretty much the same thing for picture/Sudoku cubes, and currently think the Shuang Ren is the best choice for those.
