I don't think so, no.There's no good reason the Flash franchise was still just one book after Barry came back, as both Barry and Wally could've supported a book, let alone a Flash family book or maybe even a Rogues book. Even with Rebirth, they could've just given Wally a book due increase goodwill among readers but DC just couldn't help themselves and did Heroes in Crisis instead.
There can really be only one "fastest man alive" Imho.
I'm a lot of times the guy saying "No" to replacements" but this time I think it really should have been Wally West, I mean 23 years is a long time to be the main guy.
Further... it seems that because of his titans history he's the league-r who is the most likely to stand up to batman. He has a dynamic history.
And I can't help but think that to Dc... him being a 2nd Gen character eventually got him.
Lastly, barry's sacrifice meant something for a long time.
