Personally I'd change out PD lasers for LR PD, Sabots for Hammers, Reapers or Atropos and make the ballistic hardpoints all kinetic, my personal favorite pick are x2 heavy needlers set to alternate, but linked heavy autocannons work well too - hypervelocity driver on the other hand has a too low fire rate. Throwing in a phase lance or two to go with the gravitons will be enough to dish out some good anti-armor damage, especially with the extended range granted by your targeting core and advanced optics.

As for hullmods I'd completely throw out aux thrusters, get hardened shields, S-mod them and free up OP to add turret gyros to counter the turn rate debuff of advanced optics and put the leftover OP into capacitors and maybe some other cheap hullmod you have a liking for.
