This is tough!
On the basis that i like to fight outnumbered and outgunned, there are a number of ships that I could have chosen here. That said, after much deliberation, which equates to a couple of cups of tea and a hot choccy woccy doodah, I eventually chose the Osprey Navy Issue.
The Osprey navy Issue, or NOsprey, OsNI.
The NOsprey is the feastest caldari cruiser on the block and a totally awesome bonussed missile vessel.
The fit I have chosen is as follows:

Ballistic Control System II

Nanofiber Internal Structure II
Nanofiber Internal Structure II
50MN Y-T8 Compact Microwarpdrive
Faint Epsilon Scoped Warp Scrambler
Large F-S9 Regolith Compact Shield Extender
Multispectrum Shield Hardener II
Warp Disruptor II
X-Large Ancillary Shield Booster,Navy Cap Booster 400

Rapid Light Missile Launcher II,Caldari Navy Scourge Light Missile
Rapid Light Missile Launcher II,Caldari Navy Scourge Light Missile
Medium Ancillary Current Router I
Medium EM Shield Reinforcer II
Medium Polycarbon Engine Housing I
This fit needs a Zainou 'Gnome' Launcher CPU Efficiency LE-602 for CPU.
With it's 5/6/4 slot layout - this is my go to kitey cruiser for FUN per hour!
It has a long point for when kiting, and a defensive scram for those pesky light tacklers that want to get in close and play with your missiles!
It has an XLASB for a decent tank, with extra mids for utility, and extra highs, this ship is a powerful but affordable ship. The fit I have opted for does not utilise the utility highs, however you can easily drop the XLASB, and upgrade to dual LSE and whack a couple of medium neuts for neut pressure in the highs. This ship can also swap out for HAMs if you so desire - it is very versatile!
That said, cap stability on this boat is rough - don't engage if you expect a long engagement as you will struggle with cap pressure. I find pulsing the MWD works to try to draw tackle and targets away from enemy fleets, and kill them right under their mates noses!
At range this ship is deadly. When brawling you will die. The USP of this ship is the speed and the missile projection, but watch out on those pesky reloads though and if you running in a fleet, sometimes worth staggering clips so as to not all reload at the same time, and also bringing a variety of ewar like paints for example to really help those missiles apply!
Right... now for the Battlecruiser.
As EVE is Even Better With Friends, and the OP does not mention about this being used for solo etc, i have opted for the Oracle.
With its 8/3/6 slot configuration, this is the go to high volley / alpha ship. Well priced, very simple ship to fly ... but don't be fooled, this is a difficult ship to fly well!
Triple heats sinks allow rapid fire, and with a tracking enhancer the range and tracking speed of turrets is vastly improved. With the nanos to increases its velocity/maneuverability this is a force to be reckoned with, as on overheat the MWD will take you to the insane speed of 2.5KM/s which for a ship of this class is excellent.

This is the perfect ship to sit along side the NOsprey. HUGE DPS and projection - throw this in with a long-pointer, like a Keres, and a hyena for ranged webs, and a couple of AFs, and a couple of NOsprey and you have a really deadly little nano gang.
Load short range if something gets on top of you, and stay aligned.
Fast warping, decent tank, and nanos.
Looks kinda cool too! :)
Enjoy!
