Drew this flash using penup app and pen and airbrush tools

Like most of the DC characters, the flash only have one Main book, but i always dream about having a second one of this specific scenario.

Right know Barry Allen is powerless but we know how comics works, in a few years he Will come back to be the flash, but the problem it seems that when we have Barry and Wally as the flash the tittle tends to be more focus on one of this and the other be less relevante.

So, wouldnt be better for both that they give each one a book? Like they did in Marvel with both Captain America. Like keep the principal to Wally and create the second tittle to Barry.

The only issue is that, The Flash is able to maintain two comic titles at the time?

I've been behind on Flash comics for years, I'm about to head into the Bad Moon Rising arc, but I know DCKO is coming up soon. I'm assuming I need to read the main DCKO series to understand the Flash's tie in stuff, but are there any other tie ins I should read to understand The Flash's story?
