I'd say Elektra could take out regular old police platoons no matter the number by herself. She has a habit of entering rooms filled with armed people and killing them all before a single bullet is fired. She also has this seemingly omnipresent ability to just always know where her targets are no matter their location. Combine this with all the resources she's given and I say she's the biggest threat to Gotham.
Throw in Blade/Wolverine to take out big opposing threats like possible villain/Batman alliances and I'd say the city goes down hard. And with the Hand on their side it happens pretty fast. The only real obstacle is fighting Batman himself on his own turf. And I don't see him finding a way to down Wolverine (healing factor shenanigan) with such little prep.
City loses. But Batman puts up a good fight regardless.
