Generator Brex

I was thinking one day what if Ben and Rex met one day some how by accident then Ben got Rex's DNA aquired in the I think It's called the Ultimatrix now (I don't have tv any more so it's hard to know these things ok!!!),And Ben turns into
Generator Brex, "IT'S HERO TIME!!!" and together Ben, Gwen, Kevin, Julie, Rex, Six, Holiday, Bobo, Noah, and others have a fight off with Vilgax, Van Kleiss, the Pack, and other bad guys from both shows. It would be a HUGE battle. and take a few episodes to finnish.
