Ships & Modules

I'm not sure your hesitancy to go into faction fits when you mention a faction hull or t2 BS hull...

You can a) Bling out a Vindi for roughly the same price of a b) not so blingy Kronos.

Vindi Blaster is pretty baller with a shield fit.
Vindi Rails...not so much but do able.
Kronos Blaster is VERY baller due to the hull bonus of fall off. I think with my fit I reach out to almost 60 km falloff in bastion.
Kronos Rails...eeh it works.

I'm currently playing around with the Blaster Kronos:

Highs:
4x Neutron Blaster II
2x Salvager II
1x Corpus X-Type Heavy Nos
1x Bastion

Mids:
1x Stasis Grappler
2x Tracking Computer II (Optimal/Tracking Script)
1x 500 MN Microwarp Drive II

Lows:
3x Fed Mag Stabs
1x Mag Stab II
1x Reactive Armor Hardner
1x Energized Explosive Membrane
1x Large Armor Repair II

Rigs:
1x Large Hybrid Collision Accelerator II
1x Large Capacitor Control Circuit I

The NOS adds a ~2 minutes to cap life with everything running with very nice range.
I usually charge at center point/objective with MWD while pew pewing with optimal script and null ammo. Once I get around 20 km from my desto, I shut down the MWD and when it finishes cycling active bastion to cruise to coolness/dropping a MTU.

This lands me into the thick of it, where I just wreck face with with null and switch to void if anything looks at me funny within 20 km. Stasis Grappler is liberally applied to my targets and the 2 second cycle time is amazeballs for switching to my next target.

It's not possible me to salvage faster then I pop rats, so I just leave the MTU collecting loot while I move on to the next room or w/e. Bookmark it and an hour later just come back to the wreck balls with a noctis and hoover everything up....That is if you don't run multiple accounts and have a pet noctis following you around.

I personally suggest the Hyperion. For a little more money you get a tiny dps increase, sizeable tank increase and better cap life.

While the Megathron has better tracking, it won't matter as much if you're LMJD sniping. Rats come straight at you, devaluing tracking. Not to mention I value alpha over rof for ratting. Less volleys = ammo and time saved.

Both these fits are very tight on CPU, so you'll want to plug it into EFT to make sure it works for you.

Please bear in mind, these are just fits I tossed into EFT and mucked around in. I'm sure there are more refined fits out there.
