If you could take over one existing title....

[Maxy Barnard]

I once wrote a pitch for a Hardware series, but it was more an ultimate-style retread of his origin in name of establishing him in the new 52. it's... pretty derivative.

Although I'm weirdly proud that I found a way to work in Marisa Rahm, one of the most interesting characters not only in Milestone (seriously, read Deathwish) but just straight up in comics.

as for an actual comic that exists NOW i'd like to take over, I'd both love and fear a chance to take on X-Men Legacy, just to tap into all my favourite obscure characters (CHAMBER! BLING!!) alongside the main trio of rogue, gambit and frenzy. But then I'd hate to be the dude touching a series Mike Carey did so perfectly.
