This is the ship I am currently thinking of trying. I just want to make sure that per page 11 in the Rulebook that my combat example below would be correct.

Boba Fett - Homing Missiles - Heavy Laser Cannon - Seismic Charge - Marksmanship - Mercenary Copilot - Slave 1 - Engine Upgrade - Proton Torpedo

I use Marksmanship as his action then attack with HLC at range 3 so I roll 4 dice. I get 1 hit, 1 crit, and 2 eyes. I turn the 1 crit to a hit per HLC, but the turn it back to a crit because of Mercenary Copilot. I then change 1 eye to a crit and the other to a hit. Thus getting a total of 2 hits and 2 crits.

I figured that because of me being able to pick the order the affects took place in modifying the dice this looks legit. Am I wrong?

It looks to me like you have it right.

Only thing I'd see wrong with that is that you don't get to choose the order on the HLC's change. Since it triggers on dice rolling it will always happen before you have any opportunity to change results.

Doesn't actually change anything in your scenario - everything still happens in the order you expect it to. The one place it does come into play is if you add a Target Lock (or Krassis) to your scenario and reroll a dice. Because the HLC crit-to-hit change is triggered by dice rolling, it will also trigger on any rerolls you might do.

No, you've got it right - the flipping of all crits to hits for the HLC happens immediately, then you can use effects to modify dice.

Buhallin is right, as usual. Your explanation isn't quite correct, but the end result is exactly as you thought.
