Bleach x Archer (Fate) x DxD x Others

This idea is for Ichigo, Archer, and Kisuke to basically travel throughout various universes and meet different people along the way. There's a really long fan fiction on here with around 700 chapters called Playing with Other Supernaturals. That fan fiction focuses primarily on Kisuke Urahara,Yoruichi, and various different characters from both Highschool DxD and Danmachi. I want this fan fiction to be like that fan fiction, but with Ichigo, Archer, and Kisuke. Of course, I want Ichigo and Kisuke to be post TYBW and Archer to be post UBW. They'll start off in the world of Highschool DxD, and they'll stay there for a long time before eventually moving on to different universes/worlds once Kisuke tries out dimensional travel again. The story of how Ichigo and Kisuke meet Archer will be that Kisuke was studying dimensional travel, when he accidentally summoned something (in this case someone) from an unknown dimension (the Fate multiverse) to their own. In other words, Kisuke is studying dimensional travel, he accidentally summons Archer to their world, freeing him from his contract with Alaya, and they then somehow end up in the world of Highschool DxD while Kisuke is studying dimensional travel. Kisuke later tries to replicate the method that he used to travel them to DxD, so that they can return home, but he ends up sending them to yet another dimension. This continues on for the rest of the story, and eventually they find their way home at the end. Since Kisuke's the one who freed Archer from his contract with Alaya, and he has no idea what to do with his newfound freedom, he'll decide to help Kisuke out in any way he can. He quickly finds out that there isn't much he can can help him with, so he gets recommended to help Ichigo out instead fighting-wise. He still will help Kisuke out every now and then, however, via introducing him to concepts of magecraft and having him utilize it in his experiments. You can give Ichigo a minor harem if you wish, but not a large one, and do not have Kisuke or Archer have any romance related happenings.
