Was thinking of using the tackling vigil I made.
2x injectors
1x power core mod
1x scrambler II
1x x5 prototype webber
1x MWD
1x 200mm light prototype AC
1x 'limos' missile bay
I could of course go more towards a dps setup, probably in a rifter in that case though. In either case I doubt that I'll get 12km optimal without using artillery with it's lousy tracking.
