A Rider Kick in Marvel

I want to gather your opinions on this novel. If whether I should rewrite this or not. The story up to the Spider-Men was fine, but after it was just Ace meeting hero to hero and joining their storylines. In the rewrite I want Ace to not have access to all of the Kamen Riders, so he is more balanced and maybe only let Gwen be bitten by the Spider. I also want the timeline to start at the beginning of the MCU. And if I should rewrite it, should I create another book or just post it in this same book? Comment your thoughts.
