would like to this happen due to both being among my favorite battle shonens and it would help get YYH's name out there in the mainstream.
Imagine this interactions...
Goku/Yusuke ("idiots heroes" competing with each other while saving the world)
Gohan/Kuwabara (both essentially gave up fighting to become scholars)
Goten and Trunks/Koenma (the kids would annoying the shit out of him)
Bulma/Botan (girl been helping the crew since day 1)
Vegeta/Hiei (napoleon complex)
Chi-Chi/Keiko (the love interests to the "idiot heroes"...)
