This thread might touch on some sensitive ground, but I'm hopeful this won't degenerate into another hate-fest.

DC has a lot of different characters with similar powers, appearances, status quos, and personalities. How would you change those characters to be more distinct from one another?

The easiest examples would be Barry Allen and Wally West, who ended up swapping each others character traits back and forth so much over the past several decades, the characters are viewed (rightly or wrongly) as being too similar to co-exist. How could either one be tweaked to make Barry and Wally more similar beyond Williamson's too vague idea that Barry views his speed as a scientist while Wally is more spiritual. In the end, they are both speedsters in red cracking jokes who use science and guile to foil their foes while being married to Lois Lane-types. Because of their age, Jay Garrick, Bart Allen & Wallace West have their own niche, but Barry & Wally don't because they're both going to be depicted as guys in their physical prime. Does anyone have any suggestions of how to solve this beyond the usual complaints about DC Editorial?

Another example would be Amanda Waller and the revamped Etta Candy, who's lost her more comedic persona over the years. They're now both heavy-set black women working for American Intelligence with close ties to the superhero community. Now, normally being visually similar isn't a big problem in superhero comics because the costumes are an easy way of distinguishing all those identical blonds, brunettes, and red heads with the exact same muscleman or porn star bodies. However, neither Waller or Candy wear a costume, so the only way of telling them apart is whether or not you can see freckles (Candy, unless the artist forgets to draw them) and the level of bitchiness (Waller, unless Candy is being grumpy). I don't think DC is planning on reverting Etta Candy to her former ginger incarnation or have her shout her old catchphrase every time she appears, so is there any way of making the characters more visually distinct from one another?

I also think Guy Gardner and Simon Baz are hitting too many of the same beats. Now that his brain damaged idiot days from JLI are behind him, Guy has evolved into the blue collar GL from Baltimore with a chip on his shoulder. Unfortunately, that also describes Simon Baz, except that he's a blue collar GL from Detroit with a chip on his shoulder, who is Muslim. Now, there's a lot to play with in regards to both characters, but they feel so similar they kind of make each other redundant, and, because Guy's been in more fan favorite comics, he's probably going to get used more than Simon, who hasn't really had a stand-out appearance yet. How can this be solved?
