I prefer his 90s/Current look to basically every proposed alteration to it and I would be annoyed to see him change his costume again after all the struggle to get him back to a decent place.
Aesthetic is very important to me so I wouldn't really be that interested in getting money out of my wallet if they change the design to something I think is ugly/bad.
It don't mind that his and Barry's costumes look similar and don't think having an offshoot costume gives Wally his own identity. He has his own identity, it's being The Flash. And looking like The Flash. He more than made the costume his own and I personally have always and will always associate it with him more than Barry. Because Barry was dead before I started reading comics. And when he came back his comics were not to my tastes so it didn't matter that he was back. In fact it was extra annoying that they gave him the belt design while used instead of keeping the straight lightning bolt.
I would prefer Wally's costume to stick closer to his 90's look, but I'd replace the gold with sliver. The darker metallic red was super striking. I'm not a fan of the exposed hair. Leave that look for the kids (Impulse and Kid-Flash).
I know I'm probably in the minority, but I LOVED the Navy/Silver Kid Flash look he had in the mini-series from a few years back.

I've always found Wally's classic Kid Flash outfit superior to anything he wore after. Even as a 'kid', Wally had identical powers to Barry, just lacked maturity. Don't see where covering one's hair adds any level of maturity or significance. But I don't see a change coming anytime soon. Maybe some day.
