anime/manga merging

okay the question witch anime/manga would you link would be cool with another anime/manga and if you can why my first ones are ofcourse 1-deathnote/codegeass ofcourse to see light and lelouch duke it ou 2-katekyo hitman reborn/fairytale dont know on this one jus seems funny 3-bakemonogatari crayon shinshan to see araragi react to shinchan and someone needs to teach him some manners aka senyougahara 4-akame ga kiru /fullmetal alchemist dont know just think it would be cool

1)Black Lagoon and Jormungand... actually I think a 1-shot of these 2 meeting each other already exists. 2)Inuyasha and Tenchi Muyo (old school I know,... but Ryoko x Sesshomaru just looks hot) 3)Oreimo/Haganai the same studio made both animes and the cast of Oreimo is in a cameo scene/flashback in one of that later episodes of Haganai in the 1st season Kodaka isn't some slice of life wimp like most. 4)Queen's Blade/-anything- not gonna lie, love large oppai women with tough attitudes and armor set in a fantasy realm... throw anyone in it since Claudette activated the wizard stones pulling in characters from present day Japan, the Tekken series and throughout time.
