MHA x Ben 10

What if Izuku came into contact with a severely damaged Omnitrix?
What if the Omnitrix exploded and all the DNA inside of it was moved into Izuku?
What if Izuku could become any of the aliens at will?
How would the world react to a possible 68 (because that's how many aliens Ben has turned into in all forms of media, not counting the ultimates) different vigilantes but they're all just one?
